Unity launcher doesn't recognize gnome-terminal processes as connected with launcher

[Max Bowsher]

On current yakkety:

* Open the dash
* Search for the Terminal application (gnome-terminal)
* Drag-drop it to the launcher
* Click the newly added application launcher

Observe that a gnome-terminal window opens, but rather than the application launcher having a steady illuminated background to indicate there is a running instance, it continues to pulse until it times out. Additionally, a *second* gnome-terminal icon appears at the bottom of the unity launcher, where ephemeral applications not locked to the launcher live.

I tested this in a clean newly created user account - still occurs.

Status changed to 'Confirmed' because the bug affects multiple users.

Additionally, if I hover over the gnome-terminal title bar to show the menus, the application menu is titled "Unknown Application Name".
