[Glade-users] glade mystery

[michael aps umn edu (Michael Koppelman)]

Doh, I found the problem. Apparently my realize event was deleted
somewhere/somehow so the error was telling me something correct! The
labels were not initialized. How this happened without CVS knowing about
it, I don't know. In the end it had nothing to do with this G_OBJECT
stuff.

Thanks for your help and patience.
