[pygtk] PROBLEM: gtkwarning: gdk_property_change: assertion 'window != NULL' failed Options

[Marko Tasic]

Peter,

Your code runs perfectly fine on my machine. I have installed: ArchLinux
x86_64, CPython 2.7.1, pygtk 2.24.0 and gtk 2.24.4.

Can you tell us more about your environment?

Regards,
Marko Tasic
