I get the same problem as other folks with Dolphin in superuser mode: Blank screen where files should be and an error message about can’t talk to klauncher.
Okay, I’ll just use Konqueror instead, right?
Problem is, konqueror (and many apps’ save & open) don’t see removable media (even though the hardware widget does) until I’ve opened 'em with Dolphin.
I commented on this, as I see what you mean. I had been using kde3 for su work. I noticed the Dolphin su file manager appear after a update not long ago, but never really tried it.
The release of 4.1.3 next week may bring a fix, though I’m not sure when it will be in the Suse repo’s.
