It's a bug which was added to gnome-libs on 30th May. It was fixed in
CVS gnome-libs on 14th July. I don't know which released versions of
gnome-libs it appears in. (It is in 1.2.3 which I'm using, and which I
think is still the last stable release.)

It only affects things like Glade & libglade which build the
GnomeMessageBox bit by bit.

Here's a patch which I hope works around it.

I'll probably put up 0.5.11 in a few days. I'll just see if any more
major problems turn up.

Thanks for the report (I'll let James know about the problem in libglade),

Damon
