Hmm, in theory apport should be collecting a backtrace for you but I
gather in this case it is not. However we need a full backtrace before
analysis can be done. Please collect a full backtrace - see
http://wiki.ubuntu.com/X/Backtracing for directions on how to do this
manually with gdb.
** Description changed:
Binary package hint: xorg
Here is how to reliably and repeatably crash the X server.
1. Update Lucid to the latest version, as of 2009-04-01. Reboot and log
into Gnome
2. Open xfig
3. Left click in drawing area once (to dismiss the xfig banner)
4. Press the 'c' key
5. Left click in the drawing area
6. Xserver instantly crashes (and is restarted by display manager).
This process is reliably repeatable, and I have done so several times to
gather the ltrace and straces attached.
Some more details:
- * 'c' starts the Circle tool. You can click the circle tool button instead,
and have the same result.
- * The ellipse tool has the same effect. However all other tools within xfig
work just fine.
- * xfig itself doesn't appear to be dying: it is managing to save a
"SAVE.fig" file.
- * How the %(&£"%$ is an application failure able to nuke the Xserver?
