Well, as always, the C docs are relevant.  Plus, there is "perli11ndoc"
and there are some tutorials; see the newly updated (thanks, Brian!)
<http://gtk2-perl.sourceforge.net/doc/> for pointers.

It does sound strange that the problem vanishes when you port to Gtk2 or
to C.  The binding for gtk_list_store_clear is trivial, so I think the
problem originates elsewhere.  Can you try to run your program under
"valgrind"?

  valgrind --tool=memcheck perl app.pl

If this doesn't turn up anything obvious, I'd need a minimal standalone
example program that exhibits the problem to investigate further.
