274	Qt FileDialog locks up machine with Core 2 Quad, but works with Core 2 Duo	herwigb		"On my !ThinkCentre A57 powered by a Core 2 Quad I noticed immediately after (manual) installation that the machine will lockup solidly when clicking around in the Qt !FileDialog attempting to open a file.

This happens for any Qt App I tried, most notably for SMPlayer.

If I disable one or more cores of the Quad the lockup is still there.

Today I swapped the Core 2 Quad CPU for a Core 2 Duo CPU and the problem completely goes away (that IMHO rules out a faulty installation as Silvan suspected). After going back to the Core 2 Quad, the problem is there again."	defect	closed	major	Qt 5	General	4.7.3	medium	fixed
