I'll see whether I can isolate the issue. Its a bit hard to set  
reasonable breakpoints, since the error return's are on the same line  
like the 'if' checks ;-).

Just discovered another one:

   'Could not parse response status line'

In a different virtual machine.

Yes, I've seen that working in many situations :-)

Not impossible, but a bit unlikely. Something I suspect _might_ be  
wrong is the setup of the keepalive headers. I get most of the issues  
with SOGo, if you have the time, you could try to connect

   http://sogo-demo.inverse.ca/SOGo/dav/sogo3/ (sogo3/sogo3)

and check whether you see some obviously wrong in the HTTP responses  
sent.

Thanks anyways,
