Review request for kdelibs.


Summary
-------

This patch repairs the stop button of the kauth example.

But i think there is another bug:
1: Start the long action
2: Click on stop
3: Start the long action again <-- works
4: Click on Stop
5: Now wait some seconds (~15)
6: Start the long action <-- the action returns with ActionReply::SuccessReply and the helper runs but nothing happens...
