The code that I was using:

html_fragment :content, :scrub => :whitewash

I haven't tracked down exactly why this is occurring, but it seems like it was happening when it loofah was scrubbing attributes that hadn't changed. Not sure how that makes sense though.

Thanks for the report. I will have a fix committed for this tonight.

I did this workaround for it: http://github.com/technicalpickles/loofah/tree/only-scrub-when-changed

It's still pretty unclear why it was getting a DocumentFragment way down there instead of a string though when the field wasn't changed.

active record extension returns strings, and not Nokogiri objects. closed by b88f6d5.
