Description freggy1 2008-01-26 13:16:23 UTC 
Rhythmbox 0.11.4 sometimes starts hanging when I click on the Next button.
strace shows the process is hanging in 
futex(0x81c0d8, FUTEX_WAIT_PRIVATE, 2, NULL

I think the problem started to happen after I upgraded glib to 2.15.3 and gstreamer and gstreamer-plugins-base to 0.10.15.

Each time I saw this problem, it was triggered by the same scenario: I let Rhythmbox sit idle for some time while I'm being away from computer. When I come back, I restart playback. It starts playing, and fairly quickly thereafter (a few seconds), I click on the Next button to skip the song. Then it hangs, completely, no sound is being heard.

I can't reproduce so far, and I can't see any change better glib 2.15.2 and .3
that could plausibly cause this.

I can't reproduce this either, using rhythmbox svn, gstreamer cvs, glib 2.14.5 from debian sid.

Thomas Wendt, which distribution are you using and which architecture? This still happens every time for me on x86_64 Mandriva Cooker (Rhythmbox 0.11.4, Glib 2.15.5, GTK+ 2.12.8, GStreamer 0.10.17)

Hello Frederik, I'm using debian sid x86_64, rhythmbox 0.11.2, glib 2.14.6 and gstreamer 0.10.17. I didn't test it with the current svn versions because it's too much hassle to install them at the moment.

Bug still exists in Rhythmbox 0.11.5 and GNOME 2.22 final (Mandriva Cooker 2008.1 x86_64). It only happens with the crossfade back-end is activated.

How can we help debugging this?

I could reproduce :
- Activated crossfade
- Checked to use it inside the same album
- Restarted
- Play
- Pause
- Play 
- Next

probable fix

I finally managed to reproduce this, and I think this patch should fix it.  Please test.

better patch

This is a better way to avoid the deadlock, and it also fixes a few other thread safety problems I hadn't noticed before.

I have applied the patch from comment #15 to the Mandriva package. Now every time I press 'play', 'pause', 'play' rhythmbox hangs. I'm using the crossfading backend.

But that was unrelated to the patch But even with the patch there must be another deadlock: I have added a song to the queue, closed rhythmbox and restarted it. Then I have presed 'play/pause' a few times:
# rhythmbox

Please provide a stack trace and output from 'rhythmbox -D xfade'.
