tst_QmlTests test always takes pretty much exactly 3 minutes to complete. Not sure if this is something intentional or some timeout, I'd like to look into this more:

Same thing happens in the Debian build logs. Not sure where the problem lies, but as long as it reliably resolves itself it's not really a critical problem.
