The crash seems to be related to the video decoding library. 
- Could you try to play the same broken ogv file with DragonPlayer (in kdemultimedia), "gxine" or "xine-ui" (two different media players) and check if they crash/close too ?
Regards

Marking as NEEDSINFO

Dragon Player also crashes when I pull the slider to the end of the video, but neither gxine nor xine-ui do. Do you want a backtrace from Dragon?

If I go to the Backend tab in System Settings>Computer Administration>Multimedia and put Gstreamer before Xine, Dragon Player won't crash anymore, though Dolphin stops letting me preview .ogg and .ogv files.

If I run Dragon Player from the command line, I sometimes see this after Dragon crashes: 

KCrash: Application 'dragon' crashing...
sock_file=/home/sam/.kde/socket-Hector-II/kdeinit4__0
QSocketNotifier: Invalid socket 8 and type 'Read', disabling...
dragon: Fatal IO error: client killed

Sometimes I see this instead:

KCrash: Application 'dragon' crashing...
sock_file=/home/sam/.kde/socket-Hector-II/kdeinit4__0
Assertion 'pa_close(fds[0]) == 0' failed at pulsecore/core-util.c:2166, function pa_close_pipe(). Aborting.
Unable to start Dr. Konqi

I don't know why the message changes, but maybe they make sense to someone.

About the second error message, it is related to PulseAudio (a sound server) which doesn't work properly with Phonon on KDE SC 4.3 (but it should be better on KDE SC 4.4)

A Dragon backtrace is going to be similar.
In any case, if this is not crashing gxine or xine-ui, it is not a "xine only" issue, so it is indeed related to Phonon.

- Can you install the debug symbols packages for Phonon and paste here a new backtrace (from Dolphin, or from Dragon if you want) ?
