rbutil: Fix logger segfault on application exit.

Browse source 
Getting the values from a QMultiMap() returns a list, but not the same
on consecutive calls. Thus calling it twice to get the iterators will
yield different lists, causing the iterator to fail.

Fixes a segfault when destructing the logger.
