GDB backtrace

Hello, I am experiencing a persistent GSD segfault at startup if my USB headset is plugged in.

I traced the code, and it seems that it's trying to load my usb headset as a touchscreen???!! This seems to be because it has some buttons on it, and GSD believes that the input, since it's not a keyboard, must therefore be a touchscreen, and is trying to associate it with a display device, which clearly doesn't exist.

I've attached a backtrace (it crashes trying to bind to a particular spot in the dconf/gsettings tree). I suspect this might be related to 749844, and I will try that fix, but given the completely different nature of the crash, I figure a bug report, even if that fix works, explicitly calling out the crashy nature of USB headsets, might be useful.

Upstream report @ debian : https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=789529

It should also be noticed that my headset just isn't working right - even if I plug it in after startup, it's not always showing up as a headset to gnome. I suspect that GSD is trying really hard to make it a touchscreen, and confusing pulseaudio in the process.
