The
clean up, i used Spyberus to remove the package.
It couldn't find a uninstaller and everything was removed by it, using
it's own methodes.
After the removal was completed, Spyberus reported that it left some
traces, wich weren't harmfull (it seems to do this every time that it
has to remove stuff 'the hard way').
After this, the Installed Packages-list of Spyberus was
empty.
