[Moin-user] Odd bug related to If-Modified-Since using moin 1.5.4 with CGI on apache

We need the html of that stacktrace as attachment:backtrace.html in a 
bug report on the moinmoin wiki.

I recently fixed some header related problems in 1.6 development branch.
But it was rather about missing headers than about stuff causing backtraces.
