Not exactly sure what's causing this but..I figure it's a "devs" thing

We're gonna punt on this one until the next release, because the error message we programmed in (that you're seeing) is really bad. If it comes up again after the next release, do please post it again.

I'm almost positive that's your bot trying to load Babelfish and getting confused over the change to the default languages. See if:

  @config supybot.plugins.Babelfish.languages [config default supybot.plugins.Babelfish.languages]

fixes things.

We have a WINNER!!
(Thanks!)
