Sig 5 is a Trap.

Qemu in the traces I see is mostly waiting and spawning a new vcpu.
The remaining (=the crashing) stack is in glib/spice handling.
Not seeing a direct fault in the call qemu makes.

Adding spice to get a spicy point of view on the crash as well - as I'm >=51% that the error is more there than directly in qemu.
