Title:
  Drivers can not be listed in software-properties-gtk

Status in software-properties package in Ubuntu:
  Confirmed

Bug description:
  I opened Additional Drivers to check the driver version I'm using, but it got stuck at 'Searching for available drivers'. So I went to the terminal and tried to launch Additional Drivers, and got the following output:
