I've sent a patch for this to libtermkey upstream, since it shouldn't be
calling into unibilium with a NULL pointer.  unibilium upstream also
added an assert to their side of the API to verify a non-NULL value was
given.

I haven't got a handle on this yet, but I'll keep digging.

I'll also talk to LeoNerd directly about these, since libtermkey is in
bare bones maintenance mode.  New projects are intended to use
libtickit.
