With the update released on January 19 or 20, update-notifier starts on login and doesn't crash. Nice work!

This bug happens when the program checks if it is not already running. This is done through a X clipboard hack, which fails for some reason (GDK_DISPLAY() returns NULL at line 53 of src/clipboard.c).

Why not use libunique for this purpose ?

This bug was fixed in the package update-notifier - 0.86

---------------
update-notifier (0.86) karmic; urgency=low

  [ Sebastien Bacher ]
  * debian/rules:
    - build using --as-needed to reduce the depends

  [ Dustin Kirkland ]
  * debian/update-notifier-common.dirs: update-notifier-common
    needs /etc/update-motd.d, rather than /etc/update-motd.d/hourly;
    causes this directory to *not* be removed on update-motd package
    removal/upgrade

  [ Michael Vogt ]
  * src/update-notifier.c:
    - if display can not be opened, show a propper error message
      and do not crash (LP: #317745)
  * src/apt_check.py:
    - count security updates correctly even when they are "shadowed"
      by a regular update (LP: #394958)
    - fix typo (thanks to Hew McLachlan)
  * data/update-motd-updates-available, debian/99update-notifier:
    - move updates available from /var/run to /var/lib/update-notifier
      to make it persistent over reboots
  * src/update-notifier.c:
    - make the timeout for no-activity from apt bigger (LP: #274001)
  * data/update-notifier.desktop.in:
    - better description for the auto startup (LP: #146918)
  * src/update-notifier.c:
    - use GAppInfo/GAppLaunchContext to provide startup notification
      support (LP: #46258)
