Code review comment for lp:~bilalakhtar/unity/sc-integration-phase2

Also, make sure to cover in your test this change (it should be implicit, I guess): https://code.launchpad.net/~bilalakhtar/unity/fix-sc-launcher-integration/+merge/93908 so we can merge all together (if we get the exception, otherwise you need to backport the tests to only that branch).
