This bug in ubuntu precise pangolin could be related, at least someone posted a similar backtrace. https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1021517
On further investigation, this bug does not occur when the following line is _not_ in my .xsession: xinput set-int-prop "TPPS/2 IBM TrackPoint" "Device Enabled" 8 0 which disables the ibm trackpoint on the keyboard. I tried to get a backtrace with full debugging symbols, but somehow I can't get Xorg to dump a full core.
You can try to attach gdb to the running X server, which is best done via ssh from another computer. http://www.x.org/wiki/Development/Documentation/ServerDebugging
This is the backtrace with debugging symbols: (gdb) bt #0 0x000000000044bfca in ActivateKeyboardGrab (keybd=0x186f970, grab=0x19a4bc0, time=..., passive=0) at /var/tmp/portage/x11-base/xorg-server-1.12.99.903/work/xorg-server-1.12.99.903/dix/events.c:1567 #1 0x0000000000445a00 in GrabDevice (client=0x193c200, dev=0x186f970, pointer_mode=1, keyboard_mode=1, grabWindow=<optimized out>, ownerEvents=<optimized out>, ctime=157621, mask=0x7fffe21b3350, grabtype=1, curs=0, confineToWin=0, status=0x7fffe21b3338 "") at /var/tmp/portage/x11-base/xorg-server-1.12.99.903/work/xorg-server-1.12.99.903/dix/events.c:5052 #2 0x000000000054d2d8 in ProcXGrabDevice (client=0x193c200) at /var/tmp/portage/x11-base/xorg-server-1.12.99.903/work/xorg-server-1.12.99.903/Xi/grabdev.c:134 #3 0x000000000043b531 in Dispatch () at /var/tmp/portage/x11-base/xorg-server-1.12.99.903/work/xorg-server-1.12.99.903/dix/dispatch.c:428 #4 0x000000000042a01a in main (argc=6, argv=<optimized out>, envp=<optimized out>) at /var/tmp/portage/x11-base/xorg-server-1.12.99.903/work/xorg-server-1.12.99.903/dix/main.c:295 which is the same as in https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1021517 which is marked as fixed. I didn't find anything in the freedesktop tracker.
See if the problem persists with xorg-server-1.12.99.904 If yes, it would be good if you report this issue upstream at https://bugs.freedesktop.org/ , as they are very close to release.
Still occurs in 1.12.99.904. Reported upstream: https://bugs.freedesktop.org/show_bug.cgi?id=53263
This should be fixed since xorg-server-1.13.1, please reopen if it is not.
I can confirm this works on xorg-server 1.14.1, gimp 2.8.4.
