ImportError: No module named subvertpy

[Mark Lee]

bzr 1.10 with python 2.5.2 and bzr-svn 0.5.0~rc1 can't handle what I think is a relative import in the subvertpy extension. Example:

$ bzr version
No module named subvertpy
Unable to load plugin 'svn' from '/usr/lib/python2.5/site-packages/bzrlib/plugins'
Bazaar (bzr) 1.10

  Bazaar configuration: /home/malept/.bazaar
  Bazaar log file: /home/malept/.bzr.log

~/.bzr.log:
