Bug report requested by bzr

I am trying to set up a schooltool development server.
I do this
"bzr branch lp:~schooltool-owners/schooltool/schooltool.stapp2008spring"

Afetr a delay I get lines like

File "/usr/lib/python2.5/xmprpclib.py", line 1297, in send_content
connection.endheaders()

......... httplib.py", line 860, in endheaders
self._send_outpu()

.......httplib.py" line 732, in _send_output
self.send(msg)

......... httplib.py" line 699, in send
self.connect()

.......httplib.py", line 1134, in connect
sock.connect((self.host, self.port))

File "<string>", line 1, in connect

error: (101, 'Network is unreachable')

***Bazaar has encountered an internal erro.

Please report bug ..........

I am running though an authenticated proxy, I have done an export http_proxy etc and checked it works. My host is using ubuntu server 64bit. I may need to configure bzr to use a proxy but I don't know. I am reporting as a bug cos the software asked me to.

Here is the most recent section of .bzr.log
