exceptions.KeyError: 'port' when doing Branch

Hello,

I have Windows 7 Pro x64 and everytime I try to do a local branch, I get following error. It has happened with both 2.2.1 and 2.1.2 versions. Could somebody please provide an advice?

Run command: bzr checkout http+urllib://x.x.x.x/trunk C:\Web\Data\nm\bazaar\trunk
bzr: ERROR: exceptions.KeyError: 'port'
