[Bug 2076084] [NEW] Additional drivers tab cause uncancellable operation that prevents the program from closing

[Nathan Teodosio]

Public bug reported:

Start software-properties-gtk, switch to additional drivers tab. The
program will start consuming 100% CPU for quite some time (many seconds
or minutes depending on the machine).

There is however no way to cancel the operation other than killing
software-properties. Trying to close the window or clicking Close button
hangs.

** Affects: software-properties (Ubuntu)
     Importance: Low
