Hi and welcome to the forum!
It usually comes from a problem with the permissions. Try to reset your OOo user profile
but don't transfer your personal data during the welcome process (if you had 2.x before), configuration files from the former version might corrupt the new profile.
Else, check that query
Or install the Sun version: [Ubuntu] Installing OOo on Debian and Co.
