  Installing python-nevow breaks twisted trial

Status in Divmod Nevow:
Status in Tahoe, the Lovely Accessible File System:
Status in “nevow” package in Ubuntu:
  Fix Released

Bug description:
  After installing python-nevow, the "trial" test utility provided by
  python-twisted-core fails with the following error message:

  Traceback (most recent call last):
    File "/usr/bin/trial", line 23, in <module>
      from twisted.scripts.trial import run
  ImportError: No module named scripts.trial

  Investigation reveals that the culprit is an empty "__init__.py" file
  generated by the nevow installation.  This file is placed in /var/lib
  /python-support/python2.5/twisted/plugins.  The existence of that file
  breaks twisted's plugin finding approach and causes it to fail to find
  the twisted.scripts package, which is actually located at

  I can't see how this file gets generated

  Source package: nevow
  Ubuntu release: Ubuntu 8.04.3 LTS
  Package versions: python-nevow: 0.9.26-1, python-twisted-core: 2.5.0-2build2, python2.5: 2.5.2-2ubuntu6
