Public bug reported:

Binary package hint: xorg

My HTPC has run various ubuntu's, but with 10.10 (fully up to date, but
happened since the install) its X segfaults randomly. I can reproduce a
crash eventually by simply running amarok and/or amule (so its not just
KDE or GTK related), but haven't tried any other X applications.

It takes anywhere between seconds and hours to crash once either or both
of those applications has started. And it happens both when controlling
the applications (normally via x11vnc) or when I'm not even connected to
the screen (so no vnc client).

It does however not occur with the normal mythtv fullscreen desktop
(perhaps too little changes?) and not during hours of video-playback
using mplayer.

During the latest test, I had gdb running along side of X and was going
to post the stack trace. But apparently, it hit some kind of run-away
recursion, and I gave up trying to find the last few lines of the stack
trace once I passed stack frame #130000 (I have no idea if gdb can show
a reversed backtrace?). I have taken a core-dump with gdb at that time,
which I've attached with this report.

The backtrace ended with these lines repeated basically forever:
