I finally found it. Thanks. I didn't know it was already mentioned before. According to http://en.opensuse.org/Using_zen-updater :

When zen-updater crashes System.NullReferenceException: Object reference not set to an instance of an object

For SUSE 10.1 and 10.2 In some situations, an error message shows on. It's easily fixed if you have root access and can be ignored in other situations. See the whole discussion in the thread on the subject on the factory list <http://lists.opensuse.org/opensuse-factory/2006-10/msg00256.html>

If you get an error that looks like this

System.NullReferenceException: Object reference not set to an instance of an object in <0x003d6> Novell.Zenworks.Gui.ZenTrayIcon:CheckUpdatesLoop () in (wrapper delegate-invoke) System.MulticastDelegate:invoke_void ()

This is how you can solve it

su killall zen-updater /etc/init.d/novell-zmd stop rm -f /var/lib/zmd/zmd.db /etc/init.d/novell-zmd start logout

Hi,

For some reason, every time i log on i get the following error. I cannot quite understand what the problem is.

The problem is when zen-updater is trying to fetch the updates from ZMD. The ZMD C# code is probably faulty. Bug #235045.
