I have a problem with LibreOffice (from the libreoffice stable repository) and some (not all!) .doc files. When opening some .doc files LibreOffices starts and directly closes . The same problem occurs (for the same files) with LibreOffice from the unstable repository.

When I go back to the LibreOffice version (3.3.1) shiped with 11.4 everything works fine.
Hence, if you have problems with some .doc files downgrade to 3.3.1.
