The name says it's a warning, it's pretty unexpected that it should
lead to a critical message.
One case where this is a problem is QTBUG-48488
where merely printing with "Microsoft Print To PDF" and canceling
the file dialog leads to "QWin32PrintEngine::begin: StartDoc failed"
as a *critical* message. Some Windows applications have a message
handler that shows a msgbox in case of a critical message,
and getting such a msgbox after canceling the file dialog seems very
wrong.
Task-number: QTBUG-48488
Pick-to: 6.7
