Error running autokey-gtk on command line: gi.RepositoryError: Requiring namespace 'Gtk' version '2.0', but '3.0' is already loaded

What steps will reproduce the problem?
1. Install the program using setup.py on a Fedora 19 system
2.  autokey-gtk on the command line

What is the expected output? What do you see instead?
I expect the program to launch. Instead, I see:

ERROR:root:Could not find any typelib for AppIndicator3

What version of the product are you using? On what operating system?
Autokey is version 0.90.4.
Python is version 2.7.5.
OS is Fedora 19.

Please provide any additional information below.
When I try to launch the app from "Accessories" nothing happens either.
