Personally I don't think glade installation was your problem, .. But 
moving to GtkBuilder for either new or ongoing apps is a good move, 
libglade will drop along the wayside.
GtkBuilder has been out for a while now. I know a number of large apps 
that has completed the porting effort to remove the dependency on libglade.

for some background on GtkBuilder
http://www.micahcarrick.com/05-30-2008/gtk-builder-libglade-faq.html
then have a look at his tutorial
http://www.micahcarrick.com/01-01-2008/gtk-glade-tutorial-part-3.html#2

Of course reference the documentation
http://www.pygtk.org/docs/pygtk/class-gtkbuilder.html
Then use Google to find other tutorials and other references.


You have not stated if other pyGTK applications work on your system or 
not, i.e. is it a system problem or is it a problem in your app.

I find it suspicious that the trace back shows gtk __init__.py is having 
problems importing gio

Good luck
