I get the same on GNU/Linux (openSUSE), reported previously on the mailing list:
https://groups.google.com/d/msg/serf-dev/2FezLfxgHvE/SKS313rBOY4J

• Changed state: Fixed

[GoogleCodeExporter]

The root cause was identified by Philip Martin (see mails to serf and 
subversion dev lists).

I applied his patch in r2466, and fixed a few similar cases in r2467. Thanks 
for closing this issue.
