Description abujafar 2009-10-03 11:52:11 UTC

I have just upgraded to karmic beta1.
When the option "automatically load subtitle files when movie is loaded" is enabled, totem stops responding while loading a video with subtitle file. If the option is disabled and the subtitle file is specified manually it works.
The program doesn't crash, it sticks on loading (the window is unresponsive) and i have to force quit (kill the application). In this way a crash report is not produced.

It seems that this bug shows up only during the program startup from nautilus.

Comment 1 Bastien Nocera 2009-10-03 12:58:24 UTC

Could you please get a stack trace of the hang using gdb when the application is hung?

If you want to use bug-buddy, make sure you have the debug packages installed and launch "killall -SEGV totem"

Comment 2 abujafar 2009-10-03 14:07:16 UTC

using "killall -SEGV totem" Ubuntu's apport is triggered.

I have produced this bug report on launchpad:

Comment 3 Bastien Nocera 2009-10-03 14:12:48 UTC

No permissions, attach the trace here please.

Comment 4 abujafar 2009-10-03 14:43:37 UTC

File too big to upload, grab here:

Comment 5 abujafar 2009-10-03 20:42:06 UTC

i would like to point out that this problem appears only while starting the program from nautilus. If the option "automatically load subtitle files when movie is loaded" is enabled and i add movies from Totem's movie->open menu, it works.

Bastien, are you able to reproduce the problem?

Comment 6 Bastien Nocera 2009-10-03 23:52:12 UTC

Please attach the backtrace of the hang to this bug, I don't need the rest of the data.

Comment 7 abujafar 2009-10-04 09:47:05 UTC

Could you please tell me exactly what to do and I'll do it.

Comment 8 abujafar 2009-10-05 23:37:48 UTC

The bug on launchpad is now public.

Comment 10 Philip Withnall 2009-10-08 19:42:37 UTC

Deadlock in GStreamer.

Comment 11 abujafar 2009-10-17 09:27:08 UTC

news?

Comment 12 Sebastian Dröge (slomo) 2009-10-22 09:19:58 UTC

I can't reproduce this here with gstreamer/gst-plugins-base 0.10.25 + the decodebin2 changes from Ubuntu and totem 2.28.1.

Is there anything special about the file that is used? Does it happen for all files?

Comment 13 abujafar 2009-10-22 09:46:23 UTC

Created attachment 146024 [details]
Test file

Comment 14 abujafar 2009-10-22 09:49:02 UTC

It seems to happen with almost all sub files. However try the attached file and take a loot at launchpad thread too https://bugs.launchpad.net/totem/+bug/441396

Comment 15 Robin Stocker 2009-11-02 21:46:48 UTC

I just had a deadlock with git master of the gstreamer modules and an SRT which totem loaded automatically: Bug #600479. Not sure if this is related, the stack trace is different.

Comment 16 Geert Jan Alsem 2009-11-04 10:58:39 UTC

There is duplicate bug report here: Bug #599970

I posted my findings there because I didn't know this bug report already existed.

Comment 17 Sebastian Dröge (slomo) 2009-11-06 14:18:20 UTC

Thanks for taking the time to report this bug.
This particular bug has already been reported into our bug tracking system, but we are happy to tell you that the problem has already been fixed. It should be solved in the next software version. You may want to check for a software upgrade.
