Thread List - Last Contributor - Oops

[eharding]

I know it won't be near the top of the backlog any time soon, but clicking 'Last Contributor' in the thread list view on any of the forum sections I've tried - including this one - gets the big red Oops.

Chrome on Win7 and OSX.

Same on iPad with iOS 8.3 if that helps.
