Youngone,
It looks like your serviio installation is broken. Not sure what it could be, but it is the Derby part that have problem with the database file in /usr/share/serviio/library/db/ . Possible it is a problem with access rights.

Have you changed ownership or access restrictions of folders/files on your system? All folders/files under /usr/share/serviio should have "serviio" as owner.
Have you deleted any files under /usr/share/serviio/... ?

If "serviio" is not the owner of all folders and files under /usr/share/serviio then you could try this from the command prompt:

If that does not help, try to uninstall serviio and install again: Note that while you erase "serviio" you must install using "app-serviio" to get all packages back.

If this does not help, then I would suspect that something is bad with the Java installation.
