Great update experience to 12.04

[Paul Stear]

Hi,
I just wish to thank all developers who produced this latest updat.  Although 
very slow downlods from the servers, the actual update went without a hitch.  
Well done to all.

However, I do have one problem. I have a button on the task bar "Update 
Information - KDE Daemon" If I click this I get a large black strip across the 
centre of my screen.  That's it just a strip.

Any ideas?
Paul
