Comment 4 for bug 796261

SilverLoz, this issue is unreproducible via the Terminal:

cd ~/Desktop && wget https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/796261/+attachment/2167223/+files/Test%20document.odt && unoconv --listener && unoconv -f doc 'Test document.odt' && lowriter -nologo 'Test document.odt' 'Test document.doc'

both documents look the same with the merged cells remaining merged.
