Steps to reproduce:

Boot into xen guest with default virtual keyboard (unused, I use passed through USB) . gt.hvm is guest name.
<code>
xl vkb-list gt.hvm
Idx BE handle state evt-ch ref ID BE-type BE-path
0 0 0 4 61 21 (null) qemu /local/domain/0/backend/vkbd/5/0
</code>
NOTE! No game controller attached
<code>
firefox http://luser.github.io/gamepadtest/
</code>
setting dom.gamepad.enabled to false prevents issue.
removing vkb prevents issue.

Actual results:

tab crash, see attached backtrace. Frame 12 is interesting, search for"Xen"

Expected results:

Text "Press a button on your controller to start" in tab.

Lars, could you please review and set the priority on this?

This is pretty far out of my area of expertise. Did you want Lars Bergstrom by any chance?
