At startup Log shows warning message that populating font family aliases took 1/4 second.  What code is issuing this and can we avoid this startup cost?

A quick grep of the code seems to indicate that the statusbar is the only thing requesting Lucida Sans.

Maybe check again after reversion to 5.12?

No longer get the font warning with Qt 5.12. It appears to be a problem specific to Qt 5.14.

Will re-report this problem when we upgrade Qt if it occurs again.
