HTTP status 400 'Bad Request' when using SVN 1.8, OK using 1.7

Hi,

I have been using Slik SVN on Windows 7 for several years without
incident. But recently I installed svn version 1.8.5-SlikSvn-1.8.5-X64
(SlikSvn/1.8.5) X64. At first it worked fine, for several days, but now
all svn commands which access the SVN repository are failing with an
HTTP 400 Bad Request error, for example:

C:\>svn list http://svn.kaazing.wan/
svn: E175002: Unexpected HTTP status 400 'Bad Request' on '/'

Attached is a wire shark trace of attempting the above command. From
this it looks as if /the final HTTP request was not fully written out to
the network/. I am wondering if this is a bug.

Reverting to svn version 1.7.9-SlikSvn-1.7.9-X64 (SlikSvn/1.7.9) X64
works around the issue (see attached wireshark for comparison). But I
would prefer to use the latest version if possible for obvious reasons.

Please CC me at chris.barrow_at_kaazing.com in any responses since I am not

thanks,
Chris
