No restart after 'critical' update

[lists.kho at gmail.com (Martin Kho)]

Hi,

After a 'critical' update - via update manager (kpackagekit) - is installed a 
notification pop up tells that a restart is necessary. You can chose between: 
"Restart" or "Not Now". When choosing "Restart" nothing happens. This is in 
Fedora 12 (kpackagekit-0.5.1.1-1.fc12.x86_64)

Anyone else have seen this?
