Crashes on start on Ubuntu 14.04

I can't launch touchpad-indicator, it just crashes when I try to start it. Here's the output of running xinput:

⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Apple Inc. Magic Trackpad 2 id=9 [slave pointer (2)] ⎜ ↳ Logitech USB Optical Mouse id=10 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Power Button id=7 [slave keyboard (3)] ↳ Apple Inc. Magic Keyboard with Numeric Keypad id=8 [slave keyboard (3)] ↳ Eee PC WMI hotkeys id=11 [slave keyboard (3)]

And this is the output of running xinput list-props 9:
