DockbarX repeatedly adds yakuake window; never removes it

[Adrianna Pińska]

Yakuake is a quakelike terminal app. You show it and hide it using a hotkey. DockbarX doesn't interact with this app correctly. Every time I show yakuake, another yakuake window is added to the app's window list -- but when I hide yakuake, the window isn't removed.

Eventually there are so many windows in the list that DockbarX becomes unresponsive when I try to display the list, and has to be killed. It looks like removal of the windows is failing because of an exception -- I can see these tracebacks in the console (or .xsession-errors):

Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.7/dockbarx/dockbar.py", line 475, in __on_window_closed
    dock.remove_window(window)
  File "/usr/bin/dockx", line 930, in remove_window
    del self.border_distances[window]
  File "/usr/lib/python2.7/weakref.py", line 253, in __delitem__
    del self.data[ref(key)]
KeyError: <weakref at 0x321fc00; to 'wnck.Window' at 0x32410f0>

I'm guessing that the way yakuake shows and hides has something to do with this. I haven't tested other quakelike terminals (e.g. tilda, guake); they may also be affected.

I'm using DockbarX version 0.90.3-2 (from the webupd8 PPA), on Quantal. I'm running Fluxbox, with xcompmgr for compositing.

Sorry; this is almost certainly a duplicate of #865836. Feel free to close it. I do have a dual monitor setup, so this may have nothing at all to do with quakelike terminals.

I can confirm that revision 514 to the experimental branch (https://bazaar.launchpad.net/~dockbar-main/dockbar/experimental/revision/514) fixes my bug.
