If the janitor shows nothing to clean, then it doesn't find anything wrong in your system. That's probably a good thing.
The button should be greyed out in that case, though. I'll retitle the bug to indicate that as the problem.
pvendeyse, please file a separate bug about your problem, as I suspect something else is going on there. If you can, run it from the command line, and attach the output to the terminal as well.
