crashes when pressing install. Denies reporting the bug because of obsolete packages.

Binary package hint: update-manager

1) rune@hilbert:~$ lsb_release -rd
Description: Ubuntu 9.10
Release: 9.10

2) rune@hilbert:~$ apt-cache policy update-manager
update-manager:
  Installeret: 1:0.126.9
  Kandidat: 1:0.126.9
  Versionstabel:
 *** 1:0.126.9 0

        100 /var/lib/dpkg/status

3) I press install, and it installs. Alternatively, update-manager crashes and I am able to report the issue.

4) update manager crashed when pressing install, before it asked for the password. I am not allowed to report the problem.

The problem cannot be reported:

You have some obsolete package versions installed. Please upgrade the following packages and check if the problem still occurs:

libgssapi-krb5-2, libk5crypto3, libkrb5-3, libkrb5support0

Looking in .xsession-errors I find:
Traceback (most recent call last):

checking for valid crashreport now
update-manager

This is not the first time I encounter this crash behavior. It apparently occurs when the update-manager window has been idling for a lot of time and I then press install. As if the cache somehow becomes invalid.
If I restart the update-manager or press the update button before installing; it works perfectly.
