Rawhide: Copy btw USB drives doesn't work

[Antonio M]

Tonight I wanted to make a backup copy of my holidays photos from the
travelling USB HD to my home USB disk.
So I attached to my F10 system and surprise!!! it didn't work......it
said that the destination hard drive had no permits to write (an USB
drive!!!!)

I rebooted in F9 and it worked.

What is the component to blame and to be bugzilled????
