Comment 4 for bug 298252

Using Ubuntu 10.10, Awn 0.4.0, stack applet fails to show if any desktop files use a custom icon path, something like Icon=/home/my_user/images/icons/icon.png

stack trace :
  File "/usr/share/avant-window-navigator/applets/stacks/stacks_gui_dialog.py", line 94, in _stacks_gui_toggle_cb
    return self._stacks_gui_show_cb(None)
