It happens both with the jessie and the jessie-backports version of
mumble. I'm reasonably certain I've used mumble with this headset on
this laptop before (while it was running Wheezy); maybe it didn't work
perfectly but it certainly didn't crash.
Tried on two different ARM based systems (Wandboard Quad, OpenRD Base)
and none of them segfaults when configured to use the headset, so it's
something peculiar to the XO-1.75. One thing to note is that I'm stuck
with a rather old vendor kernel (3.0.19) there whereas the two other
systems are running mainline 4.10.x based kernels.
FWIW, this is what /proc/cpuinfo looks like:
