No problem and no damage here. In the grand scheme of things, I think we are all very Very VERY happy that you made KDE happen for our little tablets. So, thank you!
Yes your running an older version of the KDE install.
Just run (as root)
ln -s /usr/local/bin/su /usr/bin/su
Now the menu shortcut should work
BTW, running this command fixed a lot; KDesktop throws an error window that shows "KDEInit could not launch '/usr/bin/sudo'.", but K3B now recognizes my burner.
I could not rip a CD. It turns out the libcdparanoia package is missing. I'm guessing that a few other packages are needed to allow MP3 ripping to work... like libmad and lame.
