PyGTK app is not quitting properly

I wrote a little PyGTK app: Workcycler

Now I have the problem that I need t开发者_C百科o hit the quit button twice for it to quit and I don't know why. I´ve tested it extensively and it allways calls all quit functions but the program simply doesn't close after the first time.

It's a pretty short script so could someone please have a look over it?

I think the problem may come from using python's timers or a part from the pygame lib (mixer).

These are the important files I think: workcycle.py and tray.py

You are running the workcycle.ui.tray.WorkcycleTray.start method twice (so gtk.main run twice ) once in the workcycler and another in workcycle.py line 20, comment that line and everything works fine.
