As of bzr 2.5 'dry-run' is not an automatically registered global option anymore. Hence querying valid options for the plugin in bzrlib.commands.options fails with KeyError: 'dry-run'. This is particularly annoying since this query is used to determine possible bash completions i.e. bzr crashes each time you hit Tab in a bzr command line.
The backtrace is as follows (Ubuntu 11.10, bzr 2.5.0-2~bazaar1~oneiric2, python-bzrlib 2.5.0-2~bazaar1~oneiric2):

I don't think this is only a problem in bzr-externals, unfortunately, because on a Precise installation containing
ii bzr 2.5.0-2ubuntu2 easy to use distributed version control system
ii bzr-fastimport 0.13.0-1 Fast-import/
ii bzrtools 2.5-1 Collection of tools for bzr
ii python-bzrlib 2.5.0-2ubuntu2 distributed version control system - python library
I am still seeing this issue (and I don't seem to even have an externals.py file on my filesystem).
