[Bug 361865] Re: twisted does not update its plugin cache properly in jaunty

[Tristan Seligmann]

This is  fixed upstream (in Debian) as of python-axiom 0.5.31-1, and I
believe all of the versions of the package currently in Ubuntu include
the fix.

** Changed in: python-axiom (Ubuntu)
       Status: New => Fix Released
