Problem with gtcd and gmenu isolated.

[Marshal Wong <mwong4 po-box mcgill ca>]

I noticed in one the bug reports for GNOME 1.0 that gtcd would crash
with some message about Imlib.  I had similar problems with gmenu
whenever I tried to click on one of the items, it would die.  I think
I've kinda isolated the problem.  It has to do with the pixmap theme.
All the other themes work fine.  So I hope this helps someone.  I don't
know enough about all this stuff to solve it though.
