Deluge download client broken on 2.0.0.2804

The Deluge download client appears to be broken on latest 2804 release.
It seems that the integration with the Label plugin is failing when setting up the label to a new torrent.

System: Ubuntu Server 14.10
Startup script: upstart

Tried with an empty deluge and sonarr configurations, but same behaviour.

2.0.0.2804 was a bug fix release to resolve an issue with Media Covers, it didn’t change anything else and it otherwise identical to 2.0.0.2788.

The error from Deluge is “Unknown Torrent”, not sure when that would happen, but this looks like a Deluge issue.

Thanks @markus101.
I’ve just seen that sonarr has automatically updated itself twice the last week, when I first started encountering the problem.
Could that be related?

No, nothing in regards to how we communicate with Deluge has changed in either release.

@markus101, again, thanks.
Just got home and now everything works again… (been off the whole day and no changes made to either deluge or sonarr).

Thanks for your support.
