serf failure

From: Ben Collins-Sussman <sussman_at_red-bean.com>

Over the last couple of weeks using trunk + serf, I occasionally get
update failures, and I don't know why. Sometimes they go away,
sometimes not. Today I tried to update a working copy from a 1.5
server on red-bean, and I get this perfectly reproducible error:

$ svn up
subversion/libsvn_ra_serf/update.c:819: (apr_err=175002)
svn: GET request failed: 400 Bad Request

I did a network trace, and while the REPORT request & response seem
fine, one of the four the subsequent parallelized GET requests is
making the server throw 400. I can't see why. Can someone take a
look? I've attached the REPORT response below, followed by the 4 GET
requests, and then the 400 response.

For some reason, my working copy is of
http://svn.red-bean.com/repos/sussman/scores/winesburg/kc-score, and
is now showing up as 'incomplete':

$ svn st
! .
! vocalscore
? vocalscore/15 Elizabeth's Death copy.mus

... presumably incomplete because every 'svn up' attempt leaves an
'incomplete' marker in the entries file. That explains why the REPORT
request is in cvs-style 'low confidence' mode, where the entire
entries file is being described.
