Thats interesting. Had same bug (Mint12).
Removed HOME/.config/libreoffice/3/user/registrymodifications.xcu. I then closed L-O and it wrote the registry file again. Same bug
So I CLOSED L-Office, deleted Go to registrymodifications.xcu Started up L-office and it wrote the file on startup and all fixed.
