update-manager crashed with KeyError in __getitem__()

[Ivo]

Binary package hint: update-manager

When I start the update manager and I want to install the updates he can't download Thunderbird:

W: Kan http://nl.archive.ubuntu.com/ubuntu/pool/main/t/thunderbird/thunderbird_3.0.4+nobinonly-0ubuntu2_i386.deb niet ophalen
  404 Not Found [IP: 213.136.29.211 80]

Then I get this bug.
