[AC-3046] Web Inspector not showing on OS X.

The issue is that when you right click on the app and try "show inspector" nothing happens, and you get a massive Cocoa error in the log output. We have tried the fix that involves re-enabling the debug pannel in the App Settings plist file, and that doesn't help.
