left-click on external disk icon opens two windows for it

[Rocko]

Binary package hint: unity

External disk drives appear as disk drive icons in the unity launcher. If you right click and choose 'Open', a nautilus window is opened for the drive.

If you left-click on it, TWO nautilus windows are opened. I only expect one to be opened.

fwiw, middle-click does nothing.
