Forum Search causes 500 error

Immediately loads the 500 Internal Server Error page, "A 500 error occurs when something on our end blows up in a bad way" etc...

eg. http://www.giantbomb.com/forums/search/?forum_search%5Bq%5D=video+player+skip

Tried multiple searches with single and multiple terms with the same result. Apologies if this has already been reported but I couldn't search for it so... give me a break ;)

Yep I get this whenever I use the search function on the forum search bar.
