bzr crashes with ErrorFromSmartServer:Error received from smart server: ('error', "'Inter1and2Helper' object has no attribute 'source_repo'") when trying to branch lp:chromium-browser

[Clint Byrum]

Trying to branch lp:chromium-browser, and I get this crash:

$ bzr branch lp:chromium-browser
Doing on-the-fly conversion from RemoteRepositoryFormat(_network_name='Bazaar pack repository format 1 (needs bzr 0.92)\n') to RepositoryFormat2a().
This may take some time. Upgrade the repositories to the same format for better performance.
bzr: failed to report crash using apport:nserting stream
     OSError(13, 'Permission denied')

Launchpad needs to upgrade the version of bzr it is using. AIUI that upgrade is due to be deployed soon.

As a workaround you can prepend nosmart+ to your URL, or get the branch on Launchpad upgraded to the current repository format.
