Backtrace in gdb after crash

This is on ubuntu 10.10 after upgrading from 10.04.
Every time i try to call emac, the x-server crashes, and I have to login again.

Following the advice, I get the debug-version. Attached the gdb output.
Comment 1 Pat Kane 2010-11-18 04:33:55 UTC
The backtrace points to line 943 in dix/dixfonts.c

	    err = (*fpe_functions[fpe->type].list_next_font_with_info)
		(client, fpe, &name, &namelen, &pFontInfo,
		 &numFonts, c->current.private);

Can you display the registers?   

A few lines of the asm code before and after the instruction that 
caused the fault would be interesting too.

Here is another report of the problem, also on an AMD 64 box:

Xorg.0.log at crashtime

1.) Started (KDE) session // with gnu session the same effect
2.) Started konsole
3.) calling emacs from konsole ==> crash

Extended data of Xorg.log

After restarting the session, this data was also added to in /var/log/Xorg.0.log.old

> Please attach your /var/log/Xorg.0.log file

Yes, it looks very alike to my crashes
Comment 8 Daniel Koukola 2010-11-30 16:13:14 UTC
I have the same problem after upgrading from Fedora 13 to Fedora 14.
Comment 9 Pat Kane 2010-11-30 17:03:49 UTC
If you are using the rpmfusion binary NVIDIA driver then you
probably have this bug:
Comment 10 Daniel Koukola 2010-12-09 19:36:53 UTC
It crashes with the nouveau driver too. But removing the following line from xorg.conf seems to help:

FontPath     "unix/:7100"
Comment 11 Colin Harrison 2010-12-15 04:52:46 UTC

is the same bug.
