Multimedia keys not working

[JK]

Multimedia keys (Play/Pause, Stop, Previous, Next) are not working for Banshee in Ubuntu 16.10. It works fine in 15.04 on the same hardware.

- Banshee version 2.9.0+really2.6.2-7ubuntu2
- Ubuntu version 16.10 (fresh install, not upgrade)
- The multimedia keys work fine for Rhythmbox and Quod Libet
- Banshee's Multimedia Keys extension is enabled in the Preferences
