Could be that this is a bug in the aging 0.10.3dev revision that is installed. There is one ticket in the Trac project that sort of touches on the same subject (http://trac.edgewall.org/ticket/2696), but it is about IE, and it is quite old. I'm not quite sure how to proceed.
That ticket refers to an Apache configuration problem - have you checked that?
I've posted a number of comments without ever seeing this error; my only guess would be it's somehow related to the recent server move...
