[Gtk-sharp-list] Problem with TreeView on Win32

[Jae Stutzman]

I'm having the same crash. I'm trying to implement a directory tree view
with little folder images...using nunit-gtk as my model, and it crashes
during show_all as well. Also on Windows.

Anyone with a good known example that works on windows?

Thanks,
Jae
