Unhappy "Database is locked" - can't use network folders


whenever I try to use a network directory as the Calibre Library Folder, the program reports a database error.

It doesn't matter if I try to choose the folder when starting Calibre the very first time after a fresh install or after "re-running" the startup wizard from the calibre menu. The network folder is empty, no books were imported.

The error messages follow at the end of this post.

The background / scenario is: I want to use Calibre on my desktop PC as well as on my Notebook and Netbook - only one at a time, no concurrent access. All machines are running Ubuntu. The eBooks shall reside on a server, which is (no jokes) a windows 7 install, so the network mounts use samba / cifs.

Any help would be very appreciated, since I really like Calibre.
