[Libreoffice] [REVIEW] Fix crash in WMF import - fdo#36991

[Jan Holesovsky]

Hi,

Can you please check and cherry pick the following commit to 
libreoffice-3-4 (libs-gui):

http://cgit.freedesktop.org/libreoffice/libs-gui/commit/?id=c4361c93de2b9661d59bc4aa799dffea7ad579e2

During the import of WMF, we are initializing a virtual device in a
thread, and it seems that other stuff that is going on that collides
with that...

Thank you,
Kendy
