* create task series
* move one occurence to other start
* see the exception created and sent (resetted attendeestatus)
--> crash after move (an QASSERT in incidencechanger), no mail is sent, but exception is created, so if you restart korganizer you can move the exception another time without any issue. And than mail is sent and attendestatus is updated etc.
(It does not crash if not building with Debug).
