ogg exemple make totem and gstreamer crash

[Xavier Verne]

Binary package hint: libgstreamer0.10-0

Steps to reproduce :

1. Open Ubuntu Karmic Live Cd examples
2. Play Aesop's_Fables,_Volume_1_(Fable_1)_-_The_Fox_and_The_Grapes.spx
3. Close application with the upper right cross OR Pause the stream
=> Application freezes
Expected results : application close.

Apport said it couldn't report from totem cause it's an external program (libgstream0.10-0)

Screenshot added of apport message (in French)

I can reproduce it as many times as I want.

I'm gonna try to debug the exact message.

Trying to further debug gstreamer0.10, it appears gstreamer plays this file quite nicely

gst-launch playbin uri=file:///media/IOMEGA_HDD/Aeso.spx
Définition du pipeline à PAUSED...
Le pipeline est en phase de PREROLL...
Le pipeline a terminé la phase PREROLL...
Passage du pipeline à la phase PLAYING...
New clock: GstPulseSinkClock
Caught SIGUSR2 - Stop request.
Caught SIGUSR1 - Play request.
New clock: GstPulseSinkClock

As you can see above, SIGUSR2 & SIGUSR1 are used to pause/start playback and it works perfectly this is not the same behavior from Totem GUI Pause button. I dont't know how totem control stream, maybe not with POSIX signals, more from within libgstreamer.

How should I investigate right now ? is it related to live cd ? To totem ? To Totem-gstreamer interaction ?

Capture-1 added, it shows Totem frozen just after Pausing (and make some other application over the window and back, so that we see X-server is not refreshing GUI).

Trying to debug from Totem right now :

# GST_DEBUG_NO_COLOR=1 GST_DEBUG=*:2 totem 2> log

I open the file from Movie -> Open menu : file

Same bug. Log file looks like this, seems to report a pb loading libpython2.6.so not avalaible :

Start thinking more and more it's not a gstreamer pb. Revert project assignment - and going to sleep.

As investigating, it seems not to be a gstreamer pb.
