So, I'm sporting the latest version of both Subliminal and Flexget and using a config that was working on a different system before, just a couple of weeks ago.
Now it seems like the subliminal plugin crashes, no matter what.
As you can see, the name is computed properly, then the unhandled error happens. Same if I try to use other providers.
Pastebin with the crash details
Here's my config:
providers: [opensubtitles, tvsubtitles, thesubdb]
