Yeah, this has been reported to the Tk author, Nick Ing-Simmons. But either he is on holiday, working on something else, or confused by the myriad levels of Gtk2 libs. :-)

He actually proposed the direction of the fix, but a fellow from the Ubuntu group, and myself, made the "educated guesses".

From my experience with linux users, most of them will not look (or find) where bugs are reported on CPAN. They will ask in newsgroups or maillists for answers.
