This is the first time that I've seen a pointer to a QHash:)
That shoudn't cause a crash though, but everything else seems to work.
Please check if it works without those two lines of AFT code. If it
does, you might try to use a QHash that's not shared across multiple
threads (i.e. use QHash instead of QHash* inside ScanResultProcessor)
