Do not crash with the null pointer, this is a hack/workaround as we

will switch to KonqUndoManager anyway. The difficulty is we would
need one UndoManager for DolphinMainWindow which we won't do/have with
KonqUndoManager so I avoid wasting my time cleaning up this bit, so
progress information might be a bit wrong in regards to the amount of
total steps...
