I just found this bug :
https://bugs.launchpad.net/ubuntu/+source/fonts-unfonts-core/+bug/1034928 ,
which addresses I think the same issue ,and fixes are marked released
,but are probably still moving up to userspace .
Still Nautilus should just call "soffice /path/to/document.doc" ,and
that works from a terminal, so there may be at least some problem with a
workaround in Nautilus.
