Comment 2 for bug 1659310

For the webbrowser case:
1) Launched Unity8 with the dash focused
2) Opened the web-browser
3) Open trust session
4) Left trust session open
5) Close browser
6) Do *not* focus dash (note if I did focus the dash first it didn't crash)
7) Open browser, by clicking on dash icon
8) Crashed as browser was launching
