Review request for Plasma, Aaron Seigo and Marco Martin.


Summary
-------

This should fix the crash in programgroupingstrategy as described by Sebastian Kügler.
The problem was that the strategy had access to startup tasks via the rootGroup.
I shortly checked all other strategies but this shouldn't be a problem there.
