When trying to launch gnome-tweak-tool I recieve this error

~ gnome-tweak-tool
gnome-tweak-tool\Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/gtweak/app.py", line 39, in do_activate
    self.win = Window(self, model)
  File "/usr/lib/python2.7/dist-packages/gtweak/tweakview.py", line 46, in __init__
    titlebar = self.titlebar()
  File "/usr/lib/python2.7/dist-packages/gtweak/tweakview.py", line 81, in titlebar
    self._update_decorations (Gtk.Settings.get_default(), None)
  File "/usr/lib/python2.7/dist-packages/gtweak/tweakview.py", line 196, in _update_decorations
    self._right_header.props.decoration_layout = ":" + tokens[1]
IndexError: list index out of range

Any ideas on how to successfully launch gnome-tweak-tool?

This post might be useful :

Go to /usr/lib/python2.7/dist-packages/gtweak/tweakview.py & find the line, that generated an error: self._right_header.props.decoration_layout = ":" + tokens[1]

One line before that there should be if tokens != None: Change that to if not tokens:

The first one doesn't account for tokens being empty, which, for some reason, is the case. Hope that helped.
