I ran into the same problem and started investigating.

Actually the header should read "Last-Modified" (note spelling). After patching the dwww script to emit the correct header the error no longer occurs with Apache. Therefore I believe the bug should be reassigned to dwww. I will reply to the corresponding dwww bug report (#781987) with the fix I applied to the dwww script. Arjan
