Bug Description

As originally reported in [1]:

When you launch Lernid, it will wait for Desktop CouchDB to start up for your user. Apparently it didn't start after 7 "...waiting for couchdb to start...", so Lernid crashed.

Lernid should display some kind of error message and gracefully close, instead of just crashing.

=============
Desktop CouchDB is not running; starting it. Removing stale, deceptive pid file.
Apache CouchDB has started, time to relax.

Thank you very much for filing this bug report. Does this still occur? When it does, does it crash Lernid or simply produce the messages above?

If this still happens, and if it crashes Lernid, the priority should be raised.

The database open (create) is now issued in a try clause to catch these kinds of errors.
