python-twisted-web package contains assertion that is always true

[Martin Olsson]

1. boot jaunty RC live CD
2. install package "python-twisted-web"
3. the following is printed:

Setting up python-twisted-web (8.2.0-0ubuntu1) ...
/usr/lib/python2.6/dist-packages/twisted/web/microdom.py:181: SyntaxWarning: assertion is always true, perhaps remove parentheses?
  assert (oldChild.parentNode is self,

Note: the semantics of assert() has changed a lot between python 2.5 and 3.0 (not sure which way python 2.6 leans)

I can confirm this behavior with package version 8.2.0-2.
the warning is not raised with python2.5

This is still occurring in Karmic. There appears to be enough information for a developer to fix this, so I am marking this Triaged.
