Package: xserver-xorg-video-ati
Version: 1:6.8.0-1
Severity: normal

After trying to minimize my xorg.conf file, X segfaults. Please note
that I am not complaining about X not being able to run with the
minimized xorg.conf, but about the segfault. An X server should never
segfault on an invalid configuration file.

I am also attaching an strace.

Greetings
Marc

Was long ago, no gdb backtrace, no reply from submitter, so closing
this bug report. If you can reproduce it with the X stack from
squeeze/sid, or from experimental, please open a new bug and attach a
full backtrace, see this page for some hints:
  http://pkg-xorg.alioth.debian.org/howtos/use-gdb.html

xorg.conf is nowadays so minimal that it's generally not needed at
all. :)
