[pulsesink] Amarok crashes on startup of application
Last modified: 2011-02-03 16:45:51 UTC
The developer Sven Krohlas from https://bugs.kde.org told me to report this bug with ALSA/GStreamer instead of at https://bugs.kde.org/show_bug.cgi?id=238357 Application: amarok (2.3.0) KDE Platform Version: 4.4.2 (KDE 4.4.2) Qt Version: 4.6.2 Operating System: Linux 2.6.32-22-generic i686 Distribution: Ubuntu 10.04 LTS -- Information about the crash: Amorak crashes the moment I click on it under Gnome using Ubuntu 10.04 Lucid Lynx The crash can be reproduced every time. -- Backtrace: Application: Amarok (amarok), signal: Segmentation fault [Current thread is 1 (Thread 0xb610d720 (LWP 3369))]
+ Trace 222038
Thread 2 (Thread 0xb026ab70 (LWP 3392))
Could you install the following packages and then get us a new stack trace please? sudo apt-get install libpulse0-dbg gstreamer0.10-plugins-good-dbg Also, what's the output of: gst-inspect-0.10 pulsesink | grep Version ?

I already have both libpulse0-dbg and gstreamer0.10-plugins-good-dbg installed. I don't know how to get a new stack trace other then the one I get when Amarok crashes, sorry. Tell me how and I will provide it for you. Here's the output of: gst-inspect-0.10 pulsesink | grep Version Version: 0.10.21

This is better. Could you also please install debuginfo packages for gst-plugin-base and gst-plugins-good. You seem to have them installed for core. Just to be sure - you are using the official packages (or the gstreamer ppa) - or do you have some self-build packages installed too.

You seem to have them installed for core. > Just to be sure - you are using the official packages (or the gstreamer ppa) - > or do you have some self-build packages installed too. I'm confused. I'm sure I originally installed gstreamer through the Synaptic Package Manager but the packages gst-plugins-base and gst-plugins-good don't show up. I found the gstreamer ppa at https://launchpad.net/~gstreamer-developers/+archive/ppa and added them to my Software Sources and proceeded to update via Synaptic. Neither package shows up even though they are listed on the launchpad site. Did the above install of ppa through the terminal as well with same results. The only similar packages I could find were gstreamer0.10-plugins-good and gstreamer0.10-plugins-base so I updated them and added the debuginfo packages for both. I assume you want me to do another back trace? Here it is if so.
+ Trace 222801
I removed all the lines that said "---Type <return> to continue, or q <return> to quit---" Hopefully that doesn't ruin the back trace for you.
Yes, "gstreamer0.10-plugins-good" and "gstreamer0.10-plugins-base" where the right packages - each disto names things according to their policies. Also this backtrace is good. Now whats not so good is that according to the trace it crashed here: static gboolean gst_alsasink_close (GstAudioSink * asink) { GstAlsaSink *alsa = GST_ALSA_SINK (asink); if (alsa->handle) { snd_pcm_close (alsa->handle); // <-- this line alsa->handle = NULL; } gst_caps_replace (&alsa->cached_caps, NULL); return TRUE; } which would be an alsa bug (?). Some questions to narrow it down: 1) can you play music with other applications? 2) what is the output from: cat /proc/asound/cards 3) does this work or crash too ? it should beeeeep (Ctrl-C to abort). gst-launch is part of gstreamer0.10-tools package on ubuntu. gst-launch-0.10 audiotestsrc ! alsasink

Hmm, there is nothing wrong on the gstreamer side. I and other people on the irc channel suspect a bug in the phonon stack. Basically if we see a crash at this position the alsa->handle is invalid (e.g. a double close). Could you perhaps try one more thing: GST_DEBUG_NO_COLOR=1 GST_DEBUG="*:5" amarok 2>debug.log --debug --nofork and attach the debug.log here (gzip it if it is too large).

After doing some research about where to find log files (/var/log), the only one titled debug.log had the following line in it: bash: cd: /var/logGST_DEBUG_NO_COLOR=1: No such file or directory

I am quite sure you see a bug in phonon. So far all the attempts have not managed to reproduce this in plain gstreamer. It would be good if you could file a bug against phonon/amarok and link it here. An investigation from that side could help to solve your problem.

Do you have a link to where I need to file this with phonon/amarok? I had initially reported this bug through the Amarok KDE Crash Handler https://bugs.kde.org/show_bug.cgi?id=238357 and the person there was extremely rude and unhelpful. I was told to report the bug here. I tried to start filling out a bug report (https://bugs.kde.org/enter_bug.cgi?product=Phonon&format=guided) with Phonon as the product but it asks what version of KDE I'm using which I'm not, I'm using Gnome and the version of Phonon (version 4:4.6.2-0ubuntu5) isn't listed. I assume the component I'm using is GStreamer and when I select that it tells me to report the bug at Qt Software. Any links you can provide me would be very helpful. Thank you so much for all your help so far. Soon as I know how and where to report this bug I will link it here.
This appears to be the same as KDE bug https://bugs.kde.org/show_bug.cgi?id=232068 This is technically due to the way phonon+gstreamer tries to use pulse but then falls back to alsa (which in turn is configured to use pulse via the alsa PA plugin). This triggered some bugs in alsa lib that cause this crash. To cut a long story short, it's an alsa-lib bug which has been fixed, but only in git. If you want the specific patches to apply on top of alsa-lib 1.0.23, I recommend these ones: http://svn.mandriva.com/cgi-bin/viewvc.cgi/packages/cooker/libalsa2/current/SOURCES/?pathrev=597366 (all the 01??-*.patch files) So i think this can probably be marked as resolved upstream but having not read all the comments I'd rather let the people involved decide that.
Closing as NOTGNOME.
