I've upgraded to KDE 4.04 using the Kubuntu Hardy Backports repo (instructions on kubuntu.org). On logging in, the process knotify4 is consuming > 90% CPU. An strace produces this:

ad nauseam

Something to do with the clock plasmoid ? not sure..

I have to kill the process so that my system returns to normal load usage. I searched for similar bugs but found none.

Is there any other info needed ?
