Bug: Errors on submit.

When attempting to submit a topic to a company (Zooomr), I kept receiving errors:

I'm sorry, but an unexpected error occured: ActsAsCached::MarshalError

I'm sorry, but an unexpected error occured: TypeError

I would attempt different combinations of emoticons, tags, and products, and submitting as a question and as a problem, to no avail.

I finally decided to 'Cancel this topic,' only to discover that every attempt actually created a topic for the company. I ended up having to go through and delete all the duplicates.

Note that even after deleting the duplicates, the counts on the page did not update (reporting 10 topics when, after deleting, there were only 2).
