Prophylaktisch, sollte sich jemand die Release Notes von 11.4 nicht durchlesen:
Update Applets with Changed Behavior
The default behavior of updating packages using updater applets has been changed. Now, along with system update patches from maintenance the applets also show updates respecting vendor-stickiness. This behavior affects users who are subscribed to third party repositories.
To revert back to the pre-11.4 behavior to have only system updates shown by the applets, set HidePackages=true in the [Updates] section in /etc/Packagekit/ZYpp.conf. WARNING: This way, you may miss security updates published in third party repositories.
