Gtk+ 3.0 problem on 64-bit Linux

[Mark Leisher <mleisher math nmsu edu>]

Before I actually start looking for an answer, maybe someone else 
already has one.

GTK+ 3.0.{10,11}
GLib 2.28

The hello-world example on OpenSuSE 11.4 64-bit doesn't work. I haven't 
looked at it in any detail, but it almost looks like events aren't being 
propagated. The button never gets focus, and none of the user-added 
signals are ever called.

In another simple example I wrote, the "draw" signal on a GtkDrawingArea 
gets called, but none of the other user-added signals ever get called.

Everything works fine on OpenSuSE 11.4 32-bit.
