The original bug report complained about LibreOffice and Evince.
I tested those specifically.
LibreOffice is in "complain" mode.
It's rules fail, but there is no user-visible impact.
Evince is in "enforce" mode.
I couldn't generate an error by just opening PDFs, saving them, and printing
them (to files).
Is this a sufficient test?
I can do a bit more, but I don't want to exhaustively test EVERY app with a
profile. :-)
