I've seen perl core dumps a few times too. They seem to be triggered by
Gnome bug-buddy, but I haven't had much time to investigate why/when
they are triggered. A typical Perl traceback here looks like this:
: (gdb) bt

This isn't very helpful for *all* Perl core dumps, but it may lead
someone towards obtaining a better traceback...
