If you launch the sample, and try to resize the TreeViewColumns when nothing in the TreeView is selected, it segfaluts. However, if you first select something from the TreeView, and then resize the column, everything works perfectly. I know that something in _onCursorChanged is causing this, but I can't quite figure out why. If you remove time.sleep from _onCursorChanged, everything works fine. Or you can remove the while loop, and everything will work also. For some reason when I have a process that takes a good second or so, and then try to call gtk.main_iteration(), it segfaults.
I have tested this on pyGTK 2.3.92 as well as 2.0.0. Any help would be greatly appreciated!
