There is no bug history thus close this. 

The contents of this bug seem to have been lost in the bugzilla disk crash.
xorg-team archives show that it orignally said:

           Summary: Xorg crashes in combination with KDE
           Product: xorg
           Version: 6.8.2
          Platform: PC
        OS/Version: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Server/general

Hello,

If I have this in my xorg.conf file, everything works correctly. 
If I uncomment the commented line, and start Gnome in .xinitrc, then Gnome
starts running. 
I can run Gnome applications (e.g. Evolution). If I in this state execute any
KDE application, X will crash. 

Other situation:I start KDE (startkde in .xinitrc). KDE starts to load. By the
time it's in the last stage of loading (there are icons indicating the
progress), it also crashes X with a signal 11 (segfault). 

In the previous Xorg version this bug was not present(atleast I didn't change
configuration and after an upgrade it stopped working).

No, I am not experiencing this anymore. I followed the steps in the
bugreport again, and was unable to reproduce. In short, probably the
bug has been solved.

I have this version now: X Window System Version 6.9.0 (Debian
6.9.0.dfsg.1-4 20060114230205 David Nusinow <dnusinow@debian.org>)
