End user experiences crash when running our app and turning on LIFX bulbs

We have a user who is experiencing a crash. They simply open our app (OnSong) and then, with the LIFX “bridge” enabled, they turn on the LIFX bulbs. This is causing the app to crash.

I have found this crash log reported that may be the issue. Can anyone provide some insight as to how we can resolve this or what may be causing the crash?
