kmail (5.9.3) using Qt 5.11.3

I've found this bug with 18.08.3 on Debian Buster.

The empty print preview is a bug in Qt 5.11.3, see bug#403159.

And the crash looks like another duplicate of bug#398577...

I believe that might've been DrKonqi's initial suggestion too, but that bug pertains to Kontact, which I wasn't using when I had the crash.

Kontact embeds the other applications like kmail, if the particular (sub-) application crashes it will look like kontact crashed.

I suppose we should mark this as duplicate then.
