If X and Gnome were StackGuarded, then you might get a present in your
syslog telling you the name of the function containing the smashed buffer:

   * if the buffer was an auto variable
   * and if the function containing the buffer tried to return *before* the
     core dump happened

I have StackGuarded XFree86 RPM's for RH 5.2 here:
http://immunix.org/StackGuard/RH52/RPMS/

Unfortunately, I do not have StackGuarded Gnome or RH 6.0 RPMs. But the
StackGuard compiler is available if someone wanted to take a poke at it:
http://immunix.org/StackGuard/gcc-2.7.2.3-14_SGc1_SG12.i386.rpm

Conversely, if someone can point us at an easy to recompile-from-source
pile of source RPMs for the necessary Gnome components, then we might take
a poike at it.
