If we can't repro this on stable (62), sending it in for a bisect. 

@lukas - to clarify, can you reproduce at all anymore? It sounds like you saw it on 61, but no longer see this on 62? Can this bug be closed?

Yes, it can be closed, I think.

As per comment#3 the issue seems to be fixed, hence closing the issue as per comment#7.
