@Andrew Starr-Bochicchio (andrewsomething):
I also am running Ubuntu 12.04 (Precise) and I confirm the crash on 'bzr help tags' and 'bzr help branches'.

Ubuntu bzr package version: 2.5.0-2ubuntu2
Bazaar (bzr) 2.5.0
  Python interpreter: /usr/bin/python 2.7.3
  Python standard library: /usr/lib/python2.7
  Platform: Linux-3.2.0-25-generic-x86_64-with-Ubuntu-12.04-precise
  bzrlib: /usr/lib/python2.7/dist-packages/bzrlib
  Bazaar configuration: /home/cdb/.bazaar
  Bazaar log file: /home/cdb/.bzr.log

Note that "bzr --no-plugins help tags" works fine!!!  Some plugin is causing the issue.
Is there any way to selectively enable or disable plugins one at a time, e.g. with a special command line option?  It would be really painful to uninstall and reinstall all my plugin Ubuntu packages for this test and especially some packages may include multiple actual plugins.
