[Glade-users] glade mystery

[michael aps umn edu (Michael Koppelman)]

Thank you for your reply.

The glade file has this line in it:

<!DOCTYPE glade-interface SYSTEM "http://glade.gnome.org/glade-2.0.dtd";>

While troubleshooting this I recompile and reinstalled everything from
scratch using the latest stable versions. I know for a fact I am linking
against the latest glib, gtk, etc. 

Nothing I do has changed this situation. If I build my code with a fresh
glade-2 against fresh everything else, I get the errors below.

Can anyone explain why I get this damn GTK_IS_LABEL assertion failure
when GTK_OBJECT is changed to G_OBJECT? As to why it changed from
GTK_OBJECT to G_OBJECT I wouldn't really care if it worked. The glade
file has the labels in question clearly defined as being of class
GtkLabel.

Thanks!
Michael Koppelman
