[Dave Borowitz <dborowitz@xxxxxxxxxx>]

I can't tell for sure, but this traceback looks like what happens when the
git client decides its POST data is large enough to gzip, which is not
handled transparently by the wsgiref server. I happen to be using a server
that does handle it transparently, which is why I haven't been bugged by
this enough to fix it.

In these cases I usually find it helpful to sniff the wire protocol with
Wireshark or similar. To test if my guess is correct, you could also run git
with GIT_CURL_VERBOSE=1 and look for a Content-Encoding: gzip header.

Hope this helps.
