You don't say which QEMU version you're using. Does it still happen
with the most recent release? Does it still happen if you build
from current head-of-git ?

PS: I think the QEMU build process should already be signing the executable,
so I'm not sure why you need to sign it again (see scripts/entitlement.sh).
