[Libreoffice] Review fix for fdo#32039 for inclusion in 3.3

[Cedric Bosdonnat]

Caolan, Michael, Miklos,

Could you please have a look at the patch attached to
https://bugs.freedesktop.org/show_bug.cgi?id=32039 ?

I'ld like to push that fix for 3.3 as the bug is a regression introduced
by our rework of the RTF export filter.

Regards,
