if you want to find out whether anything bad will happen by running Konqueror as root, then we will save you the time and trouble, and say, yes, sooner or later, bad things happen.
I always find this sort of declaration a little exagerated, and funnily no one ever seems to answer: "why?"
To me there is little difference between running an app with sudo and running it as root. If I need to do a lot of work as root, I just log in as root (and I've set up the root desktop with ugly, flashy colours so that I know I'm there). Letting you login as root with a GUI is a nice thing of TDE.
Of course no one should "live" as root (although I did that for one year when learning how to use Linux, but that was not a "production" machine), but why make people believe that as soon as they are root, they are doomed?
People live as root on Windows machines and while this is a dangerous thing, bad things don't always happen.
I just feel that this "never run Linux as root" is some religious mantra, and who does not respect it is an heretic.
