I get this error when trying to launch Lutris in Ubuntu Mate 16.04.
pizzadude@pizzadude-thinkpad:~$ lutris
Traceback (most recent call last):
File “/usr/lib/python3/dist-packages/lutris/gui/application.py”, line 152, in do_activate
self.window = LutrisWindow(application=self)

apps = get_games()

if app.get_executable().lower() in IGNORED_EXECUTABLES:
AttributeError: ‘NoneType’ object has no attribute ‘lower’
Any fix?
