Bug#431114: update-manager: Update-Manager crashes when started

[Sean]

Package: update-manager
Version: 0.42.2ubuntu22-13
Severity: important

Upon launching Update-Manager, the "Examining Your System" window
appears, but when it finishes (the status bar reaches full), both the
main window and the status window disappear. I ran update-manager from
the command line and got this error:

$ sudo update-manager
/usr/lib/python2.4/site-packages/apt/__init__.py:17: FutureWarning: apt
API not stable yet
  warnings.warn("apt API not stable yet", FutureWarning)

    action_group = apt_pkg.GetPkgActionGroup(self._depcache)
AttributeError: 'module' object has no attribute 'GetPkgActionGroup'

I remember that there was a python update recently. Could that have
caused the problem?
