My sublime-text 2 editor no longer starts when I click it's icon in my dock.
The icon does the normal slow pulsing for a while (unity) but nothing seems to load.
How can I determine why sublime has started failing?
UPDATE
Output of $ cat /usr/share/applications/sublime-text-2.desktop
#!/usr/bin/env xdg-open
