Some reproduction questions: can you reproduce this with a more recent
version of Subversion (1.3.2, or else a later beta or development
version)? What about if you upgrade to Apache HTTPD 2.2.x?
If the problem goes away, then the answer is just to upgrade some
software I guess. If not, I'd be very interested in a dump of your
repository to try to reproduce on my own.
Thanks
