Thanks, That seems to work!

But now I might have found a bug: I have some context menus for my 
applets, by which they can be removed.
I connected the triggered signal to the applet's destroy slot. If I 
remove two applets on after the other, then the application crashes. If 
I wait for a few seconds, that everything's ok.
Is there an explanation for this?

Cheers,
Oszkar
