All of the qDebug() messages are of the "this is not supposed to happen"
variety.  The one above does not trigger on windows or linux, and if I
understand correctly does not trigger on OSX with Qt4 either.   Whether
it points to a problem with Qt5 per se or to a larger problem with OSX
font handling I do not know, but either way it really is fingering a fixable
problem.  If nothing else it should allow OSX users to diagnose
semi-quantitatively whether tweaks to their font setup improve or degrade
the performance.
