Yeah, that's basically what I had (although thanks for the _WITHDRAWN
hint). Unfortunately I can't get a window-state-event to fire at all.

Are you sure your method works? I just added the following line to the
top of /usr/lib/python2.5/site-packages/gpodder/gui.py:

        print "%s - %d" % (event.type, event.new_window_state)

Starting gPodder from the terminal doesn't result in any output when
backgrounding the app, or minimising the window.

On Diablo (latest SSU) it doesn't seem to be working at all; although
confirmation would be appreciated before I create a test case and
raise a high-priority bug.

Cheers,

Andrew
