RSS and SEEN are completely useless in their current form. The problem with RSS and SEEN is that the whole database handling is not correct. You'd need to run some sqlite commands on every startup, because the db will always be locked on start:

connection.commit() sqlite3.OperationalError: database is locked (Fixing the mentioned line only doesn't work, it'll come up with an error everytime the db is called.)

Now if you open it manually and it works, the db file will be corrupted as soon as there is more than one access at the same time. This might happen when you have assigned different feeds to different channels and the feed selfcheck is executed. I tried to tweak it by adding a timeout to "sqlite.connect(self.db, timeout=10)", it may help, but even this will not work reliably when there are lots of feeds assigned.
