Bug Description

Earlier, I've noticed some installed apps weren't appearing in the launch. The noticeable one was Unity Tweak Tool, so I typed it in the Terminal to see if it'll launch, which it did but also gave an error:
"/usr/lib/python3/dist-packages/UnityTweakTool/__init__.py:40: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.
  from gi.repository import Gtk"

It appears to that something, like the Gtk isn't configured properly, or not configured at all and doesn't know which one to choose.
I have two folders, gtk2 and gtk3 in my home folder. It appears I have two installed (which were most likely installed with a fresh install of Xenial) which is causing the conflict.

PS: The Unity Tweak Tool, now shows up in the launch; I'm not sure what was changed, but a few things that weren't showing before, are now. My guess is installing extra packages for apps may have fixed them?

OS: Ubuntu 16.04 (Xenial) x64
App Version: 3.18.3

- Blossom.
