This is caused by an API-breaking change in PyGTK:
https://bugzilla.gnome.org/show_bug.cgi?id=653462
" Change Gdk.color_parse() to not return a tuple, instead just return the created color or None if it wasn't possible to parse the name into a color.
This keeps compatibility with PyGTK but breaks the current API.
