[Libreoffice] [REVIEW] fdo#39159 selection and writer print dialog preview crash

[Caolán McNamara]

A most-annoying bug: https://bugs.freedesktop.org/show_bug.cgi?id=39159
My plausible fix.
http://cgit.freedesktop.org/libreoffice/core/commit/?id=cd690d2e72be410058376c416a40ff5d918fb0f7
that I'm proposing for cherry-picking back to 3-4.

I'm not delighted by this as a solution, I'm rather a hater of the
writer nest of views and shells, but I think it will do the job.
Definitely stops the crash, worst case scenario if I'm wrong is that
some selection-related print scenario might toggle some current view
options like "show field codes" off or something of that nature.

As an aside our own fedora abrt crash capturer has a constant small
trickle of OpenOffice.org as well as LibreOffice related crashes coming
from writer print with this relatively new renderer, so its apparently
an inherited set of problems.
