Ok, I got a core this time. Here's the trace from the log and the bt from the
core.
Not sure if it's good or not:
Loaded symbols for /lib/i386-linux-gnu/libnss_files.so.2
Core was generated by `/usr/bin/X :0 vt8 -nr -nolisten tcp -auth
/var/run/xauth/A:0-7D4BUa'.
Program terminated with signal 11, Segmentation fault.

(gdb) bt

Either way, it looks like I'm on the wrong list now, where do you recommend I
go?
Thanks,
Marc
