Using a fresh install of 11.4 KDE, when I download an app from a website (for example google talk plugin) KpackageKit opens it by default and promptly crashes.

Then after KpackageKit crashes, everything else crashes. Since the menu and konsole crash, I have to do a hard reboot to get out. Then, after that, neither 11.4 nor the OSes will boot. (I fix grub, though, with directions I got from
caf4926 last year).

For the time being, until I find out what to do, I've uninstalled KpackageKit. I then selected Yast as the application to install google talk plugin but got no response.

Any help would be deeply appreciated.
