Your welcome. I suspect there's only a couple things that could cause this issue.
Database corruption. Permissions issue. Running the application using sudo is a terrible idea, so please don't do that. Database corruption shouldn't really be an issue, but it can happen sometimes. Anyway, glad it helped. -- You received this bug notification because you are a member of Ubuntu Studio Bugs, which is subscribed to font-manager in Ubuntu.
