I cannot confirm this bug now: I don’t get any "internal error", although the transclusion of these pages makes appear plenty of awful <translate> tags -- perhaps this will be improved in the future, but for now you can transclude "{{:Wikimedia Highlights, August 2013/en}}" to get a proper result.

FWIW, I don't get the error any more myself now.

Yes - that wasn't the issue though; it was definitely an internal error. I don't remember if I tried transcluding /en pages too.

This is almost certainly duplicate of bug 44608.
