Bug Description

This is a bzr-gtk gdiff issue. The diff works, but an error happens when the window is closed. This may be the same kind of issue I fixed in gcommit where the callback is called while the window is being destroyed. In that case, The treeview still existed, but it's model and state were None.

To reproduce on precise with trunk:
Branch any project
bzr gdiff
See no changes
close the window
See TB

Traceback (most recent call last):
  File "/home/curtis/.bazaar/plugins/gtk/", line 391, in _treeview_cursor_cb
    specific_files = [ self.model[path][1] ]

If this issue is like the gcommit issue, I think I can fix this issue in two hours.
