Public bug reported:

Binary package hint: xserver-xorg-video-radeon

In Lucid Kubuntu Xorg crashes from time to time. Before Lucid this
machine had Intrepid Ubuntu and as far as I remember Xorg has not
crashed for more than a year.

According to /var/log/Xorg.0.log the call stack looks like this

Segmentation fault at address (nil)

I enabled apport, but if did never catch the Xorg SEGV (It caught other SEGVs so I don't know what I did wrong)

I built matching debug packages (the ones from the repositories  cannot
be used because of https://bugs.launchpad.net/bugs/562418) but still the
call stackin gdb is always useless:

(gdb) bt full                                                                 
#0  __memcpy_ia32 () at ../sysdeps/i386/i686/multiarch/../memcpy.S:75         
No locals.                                                                    
#1  0x00000000 in ?? ()                                                       
No symbol table info available.                                               


I will run apport-collect and attach a few log files.
