U3 Flash drive hangs Ubuntu when right-click on desktop icon

[Joaquín Ignacio Aramendía]

I think the problem is related to how the drive is recognized. In Ubuntu Natty, nautilus recognizes U3 drives as "software" and freezes all system trying to open it. I suggest that the U3 software is not recognized and just is treated as a single USB Flash as it makes the whole system unusable.
I follow this steps:
 - Insert an U3 Usb flash drive.
 - try o unmount/extract it
 - Ubuntu freezes/slows badly until I remove the drive (just deataching it from the netbook usb port)

Also Ubuntu freezes in this scenarios:
1) - Insert an U3 Usb flash drive.
      - right-click on desktop icon.
2) - Insert an U3 Usb flash drive.
      - Open Places > Computer. Double click on the U3 Drive.
3) - Insert an U3 Usb flash drive.
      - Double click on the U3 Drive icon on desktop.

The drive is unusable under Ubuntu even as a standard flash drive, if you try to do anything from the desktop icon (right-click, double-click) then will freeze nautilus, the gvfs daemon and notification modules got 100 cpu usage until the device is removed by deataching it from the usb port.

Under Arch with GNOME 3 this does not happen. The device is just recognized as a normal usb flash drive and U3 "system" is ignored completely. Did not test it in other Ubuntu versions.

Thanks in advance.
