Code review comment for lp:~elementary-apps/audience/about-in-quicklist

I meant in a testable state. I was trying using "gapplication action" to launch the about dialog instead of the --about command line flag, and see if that would be the problem. It's not testable because the GLib package in Trusty doesn't ship the gapplication binary for some reason, which should for GLib 2.40, but that's another matter.

I may end up reverting those commits, depending on if/how the crash issue is resolved.
