Does it work if you call gtk_init() before gdk_threads_enter()?
I wouldn't consider the code below normal, though I can't
*offhand* think of what problems it would cause.
If not, then install the -debuginfo packages, get a decent backtrace,
then report it either in Red Hat bugzilla or GNOME bugzilla; I
don't think either one is particular more right then the other;
it probably would be an upstream bug, but it's hard to say.
