Hi!
May anybody explain to me why do the files specified in the subj. appear in the root dir every time I reboot a computer?
I has an ArchLinux-64 at the computer.

There's a report here: https://bugs.kde.org/show_bug.cgi?id=356098 - No response from the developers yet.

I've had no issues deleting those files when they build up, although they will start to mount up again over time.

I suppose they get created when opening dolphin through kdesu or similar.
