The crash is reproducible with the final LiveCD of 10.10, zooming into a
x264-Video. Zooming out (image gets smaller) works. Other video formats
(xvid in .avi or .ogm) do not crash.

xine chooses "xv" as video_out plugin. With video_out="opengl" the crash
does not occur, because zooming is not possible then. With
video_out="xvmc" xine crashes the x-server immediately after its start,
even without a video!!

So far I guess:
As totem is also affected, it seems to be a problem with an underlying x264-library feeding reckless dimensions through xv to the the driver xserver-xorg-video-ati, which then crashes. If this is true, then both the x264-library and the xserver-xorg-video-ati would need a fix, while the latter is more important to avoid future crashes caused by problematic libraries. I'll try to find the guilty file by mixing versions of Maverick and Lucid, where this bug did never occur.
