All of a sudden my usb disks stopped mounting for me, only as root. No hope with anything on the Internet. I had to run a new kernel 3.17rc5. It gave an error, and lots of bling on the startup, but it works ok. I can now mount my usb sticks with my ordinary user.
Dolphin is now giving extra options, so I think that was a problem.
Update: If you want those search options then install 'baloo'. Then go away for a day. :)
