 I've now made it crash while it was running with -core.  It took me some time
 to find the core file (it would be good to mention on that page that for (new)
 gdm, it is in /var/lib/gdm3).
 
 Anyway, I attached the gdb logs of the bt and bt full commands.  I don't know
 why it says it has no symbol table; I did install the -dbg package.  Should I
 do something to load the symbols from that package?
 
That trace doesn't seem to have debug symbols for the driver.

I didn't realize there was a per-driver debug package; it would be useful if
this FIXME in the gdb document at least mentions that.

Hopefully the attached file is better, even though it still complains about
some missing symbols.  Please tell me what to do or install if you need more
information.

Thanks,

Bug#724944: xserver-xorg-video-intel: segfaults when trying to play movies

2013-09-29 Thread Bas Wijnen 
Package: xserver-xorg-video-intel
Version: 2:2.21.15-1+b1
Severity: grave
Justification: kills entire session; including applications running on it, 
which likely results in data loss.

I can reliably crash the X server by starting almost any video with almost any
player.  At least mplayer, xine, totem, and xawtv (showing images from my
webcam) have managed to crash it.  Log file attached.  If you need debugging
symbols or anything like that, let me know how to generate it and I'm happy to
send it.

The only way I have currently found to play video without crashing X, is using
mplayer -vo x11.  I think that disables a lot of hardware acceleration, but I'm
by no means an expert on this topic.

Thanks,
Bas

No, that isn't data loss.

I sure lost data on it, but I'm not arguing that the lower severity is
reasonable.

 Please provide us with a backtrace. Some hints are available at:
   http://x.debian.net/howto/use-gdb.html

The backtrace was included in the log file, hence I didn't think it would be
useful to generate another one.  I can see how it would be helpful to have a
trace with symbols, but I needed help with getting those; that was on the page
however, so I installed xserver-xorg-core-dbg.  For that, I needed to upgrade
to the +b2 version, which doesn't crash anymore...

 Also, where's the bug script output?

I don't have a proper mail system set up on this host, so reportbug doesn't
work well (I think).  But you're right, I should have generated that list.
Sorry about that.

Thanks for your quick reply and sorry for the noise,
Bas
