Re: Xwin stackdump while logging into RH8 with KDE as window manager

Harold,

I  have attached the output from the gdb run and, even thought they have 
not changed much, the stack trace and log. Please not that I have not 
downloaded source, so all you have is the file and line number where the 
violation takes place. I my having the source here can help with this 
please let me know.

Thanks,
Joel
