window icons don't go away [awn-applet]

[Kived]

Using AWN applet, I have had problems with some window icons not disappearing when the associated windows were closed. Only some windows are affected, primarily xulrunner applications that I am running in a 32-bit chroot (on my 64-bit system), and Eclipse IDE windows (using IBM JRE). The xulrunner app is the worst as I am continually closing and restarting the app, so I end up with a window list with 30 window entries, none of which are actually open anymore.

This does not happen in run-in-window mode as it seems to be a problem in the AWN applet itself. I ran AWN from a terminal to see the output and found this:

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/dockbarx/dockbar.py", line 461, in __on_window_closed
    dock.remove_window(window)
  File "/usr/share/avant-window-navigator/applets/DockBarX/DockBarX.py", line 138, in remove_window
    del self.border_distances[window]
  File "/usr/lib/python2.7/weakref.py", line 253, in __delitem__
    del self.data[ref(key)]

I got it working by wrapping 'del self.border_distances[window]' in a try-except block, but I don't know much python and that may or may not be the best solution. But either way, I'm attaching my tiny little patch. :)
