Comment 2 for bug 215426

That's a good idea -- it does look similar. I'll take a look tomorrow (Friday) and see if I find anything.

Another piece of information is that I'm using NTLM Proxy (http://ntlmaps.sourceforge.net/) and if I enabled debugging, the problem goes away. I am serving the files through a Pylons app, but also tried Apache 2.x for a sanity check. Pulling the same repository through Linux seems to be fine.
