another unhelpful error with Trello Importer

[Jeffrey Knurek]

I'm trying to use Trello Importer Plugin for JIM to import our existing issues into Jira. I previously had a problem with special characters in the Trello List name. I've gotten past that but am now getting this vague error when trying to import the issues:

2014-05-20 09:43:48,749 ERROR - Unexpected failure occurred. Importer will stop immediately. Data maybe in an unstable state
