Nautilus inconsistent usb-stick-write-protect handling

Nautilus handles a hardware write-protected usb-stick wrong after restarting the computer.

1. Insert only one (this is important) usb-stick which is hardware write-protected.
2. Try to copy a file to the usb-stick (no success => ok)
3. Set the write-protect off => One can't copy a file (error-message : usb is write-protected) => Not ok
4. Remove the usb-stick and plug the stick back in => One can't still copy a file, write-protected-error-message ??
5. Remove usb-stick and plug another one in => one gets the same error-message (although other usb-stick)
6. One has to log-out/log-in before the stick can be used

If you use at first a non-write-protected stick and then afterwards a write-protected stick, then everything behaves normal.
