Bug#431655: xorg restarts when playing video

[Carl Fink <carl@fink.to>]

Package: xorg
Version: 1:7.2-5
Severity: important

When playing back video using totem (either totem-xine or totem-gstreamer
from debian-multimedia.org), xorg will unpredictably restart.  The crashes
seem to be most frequent when totem is playing a playlist (not a single
file), and to happen during the transition from one file to another, or
whenever I task-switch either away from or to the totem window using the
keyboard (alt-tab).

I tried VLC as an alternative.  Playing video back with VLC, xorg will also
sometimes crash on transitions as above, and crashes 100% of the time if I
change the hotkeys in the VLC preferences and click "Save".

In order to test for hardware problems, I booted my tower using a Knoppix
CD.  Knoppix doesn't include totem or VLC, so I played several videos with
Kaffeine.  There were no problems whatsoever.

I then booted back into Debian Lenny, installed Kaffeine, and tried to play
the same video files.  Before the Kaffeine window even opened, xorg crashed
again.

Andrew Sackville-West reports that he can reliably crash X by dragging an
active mplayer window from one monitor to another.  Andrew's and my
discussion on debian-user can be read starting here:

http://lists.debian.org/debian-user/2007/07/msg00043.html

That thread includes Backtrace reports from the xorg crashes.

Relevant versions on my PC:

totem-xine: 2.16.5-3
vlc: 0.8.6.a.debian-6
kaffeine: 0.8.3-1

I'll be glad to provide any other information that will help.

Thanks.
