Comment 5 for bug 733136

I get the same error message, "bzr: ERROR: exceptions.UnboundLocalError: local variable 'lock_url' referenced before assignment", but when trying to run Pull from Bazaar Explorer, not when saving configuration. Full text:

Run command: bzr pull
bzr: ERROR: exceptions.UnboundLocalError: local variable 'lock_url' referenced before assignment
