Is there anything you can do to reproduce this crash? Does it happen every time you remove this drive?

[Sebastien Bacher (seb128)]

it's still happening in the natty beta1 version, just got it today while right clicking on an usb stick on the launcher and selecting eject

it's crashing on this line
