App icons remain in Dash after uninstallation, or total inability to run app from Dash.

[Patrick Bowen]

I have two icons which remain after unistalling the application. This also happened on my previous 32bit Utopic with Skype creating two icons: one which worked, and one which was like the screenshot attached.
