That's fine, but I don't think it's release-critical. Could you file a
separate bug for that part, please?
(I also think that's a qemu bug, more than an application bug; it
shouldn't let you emulate a CPU that isn't going to work. I don't think
applications should be expected to cope gracefully with an emulated CPU
that claims it can support instructions but does not actually execute
them correctly, which I think is what's going on in this case.)
