bzr commit on a split tree crashes

After using 'bzr split', trying to 'bzr commit' changes in the subdir crashes.
Here is an example from a test repository I made:

$ bzr version

  Python interpreter: /usr/bin/python 2.4.4.final.0
  Python standard library: /usr/lib/python2.4
  bzrlib: /usr/lib/python2.4/site-packages/bzrlib
  Bazaar configuration: /home/wjlanda/.bazaar
