SVN commit 1204252 by gateau:

Reverted "Do not crash if an job was deleted in a slot connected to result()"

David explanation:
"""
In addition, you added a guard in kjob.cpp itself, but what about the moc-
generated code in between? When deleting the sender, we then go back to the
signal emission code inside of a deleted object...
