Ok. That's what I did. the results are attached.

There are 3*3=9 files attached. Their names indicate the conditions under which the error showed up:

 - The files triggered.* com from a crash triggered by calling 'dmesg 9' as
   non-privoleged user. Yes, it is 'dmesg 9' not 'dmesg -n 9'.
   
 - The random.* files come from a crash that I did not consiously trigger. I
   bet I did, but I dont know why or how.
   
 - The normal.* files come from "normal" operation. I include them, because X
   seems to terminate with a SEGFAULT when the windowmanager disconnects and my
   session terminates.
 
Suffices:

 - The files *.log.bz2 contain the logging of the gdb session.
  
 - The files *.dmesg.bz2 contain dmesg output from after the crash.
 
 - The files *.Xorg.0.log.bz2 contain Xorg.0.log from after the crash, at that
   point in thime had been renamed Xorg.0.log.old, because the X-server was
   restarted.

I hope this helps you! Please ask in case you need further information!!!

Kind regards,
and thank you for looking into this!

Stefan
