Comment 1 for bug 1001784

Is there a more complete traceback in .bzr.log ('bzr version' will tell you where it's located for you) ?

This smells like a PYTHONPATH including the current dir and loading unexpected modules (I can't remember any module named 'dir' though).

Alternatively running 'bzr -Derror info' should display it or, if you feel adventurous, 'BZR_PDB=1 bzr info' should give you a pdb prompt.
