The issue with the notification icon is driven by 2 issues. In Kpackagekit
somehow defaults got set to Hourly/Security. Packagekit is having problems
with notifications. Fix should be coming soon.
I just found out I have a stack of updates waiting but it seems the
notification icon is not working. I normally use Smart for the KDE
updates and Packagekit for the rest of the system.
Can anyone confirm this before I dig deeper,
I have tried everything to get it to work with no luck so far. I'm not
sure if this would be a KDE RC issue or not and as to when this problem
appeared I'm not sure.
