A qemu segfault? Can you post the reproduction recipe?
I tried my first thing and it crashed. This is enough:
qemu-img create -f qcow2 -o backing_file=gluster://test1.qcow2,backing_fmt=qcow2
test.qcow2 1M
qemu-img convert -f qcow2 -O raw test.qcow2 output.img
I just haven't had the time to check why and where it segfaults...
