internal error when executing "bzr branch lp:python-mode"

[Patrik Jonsson]

It's my first time ever using bzr, and the first execution resulted in an "internal error" that says to report it, so I do:

[pjonsson@sunrise02 ~]$ bzr branch lp:python-mode
bzr: ERROR: exceptions.AttributeError: addinfourl instance has no attribute 'getheader'

You're running a really old version of bzr - newer versions should work better and faster on your system.

Ok, thanks. I'm not in charge of maintaining the machine but I'll tell
the sysadmins to upgrade.
