I've installed screenlets on my system and included:
sudo apt-get install screenlets-pack-all
The Screenlet Manager comes up with many screenlet choices but when I try to kickoff any specific app I get this:
usr/lib/python2.7/dist-packages/screenlets/backend.py:166: Warning: Source ID 63 was not found when attempting to remove it gobject.source_remove(self.__timeout)
and this continues with Source ID 64, 65,etc...and the app never launches.
There must be some python problem...?
