FYI: you don't really need a new thread here, just use:
self.timeout_add(1000, self.get_pictures)
and return True at the end of get_pictures.

The setup() method of the window model class should be called from
do_manage_client already.
(see the ugly call_setup invoked from the instance __init__ method)
The unmap case is a little bit more difficult, you could try commenting
it out in _process_unmap_window and see what breaks...
