Cannot branch a repository (AttributeError)

[Valentin Lorentz]

Hi,

When I run "bzr branch", I get this:

$ bzr branch lp:~ubuntu-fr/ubuntu-bots/ubotufr
You have not informed bzr of your Launchpad ID, and you must do this to
write to Launchpad or access private data. See "bzr help launchpad-login".

*** Bazaar has encountered an internal error. This probably indicates a
    bug in Bazaar. You can help us fix it by filing a bug report at

Thanks for the report, this appears to be a regression with the trunk version of bzr.
