Session handling breaks AutoAdd plugin

[Elberet]

Symptom:

17:41:08.104 [ERROR   ][deluge.plugins.autoadd.core   :295 ] Disabling '/torrent/watch', error during update: [Failure instance: Traceback: <type 'exceptions.KeyError'>: -1
(snip!)
/usr/lib64/python2.7/site-packages/deluge/plugins/AutoAdd-1.02-py2.7.egg/deluge/plugins/autoadd/core.py:242:update_watchdir
/usr/lib64/python2.7/site-packages/deluge/core/torrentmanager.py:406:add
/usr/lib64/python2.7/site-packages/deluge/core/torrentmanager.py:289:get_torrent_list
/usr/lib64/python2.7/site-packages/deluge/core/rpcserver.py:497:get_session_auth_level

This exception occurs whenever the AutoAdd? plugin's update_watchdir runs, finds a new .torrent file and tries to add the torrent while Deluge is running in daemon mode and no client is connected. At that time, the RPCServer's self.factory.session_id value is either -1 or the ID of the session that last disconnected, while RPCServer's self.factory.authorized_sessions is empty, resulting in a KeyError?.

This occurred on a Gentoo Linux box running Linux 3.0.4-gentoo-r1 x86_64 on an Athlon 64 X2 with Python 2.7, twisted 11.0.0. Deluge is based on commit 7227c97c, it is running headless and as a non-root user.

I have attached a quick and very, very dirty workaround.

fix session lookup error

This one still exists with 569dd0c58588549188dd44912e3338866c3a6dc2

Patch for latest master

[non7top]

Latest patch "fix_session_lookup_error.patch (1.3 KB) - added by non7top" doesn't resolve the problem. I think I'll have to switch back to some earlier revision.

[non7top]

Please commit to master

I've just committed this fix:

Can you please test it?

Looks like this fixes the problem. Thanks.
