Hi,
We've noticed the following error during Windows install when using the
latest qemu from HEAD:

The relevant git commit used was:
04/03 01:41:37 DEBUG|base_utils:0077| Running '/usr/bin/git fetch -q -f -u -t
git://git.qemu.org/qemu.git master:master'
04/03 01:41:41 INFO | git:0153| git commit ID is

There's a 2.1 core dump file saved in our results server, if there's any
interested in it by contributors outside Red Hat, I can ssh it to some box, as
requested.
So, even though it might be some flag we're using that is
obsolete/deprecated/whatever here, qemu shouldn't crash.
I'm available to provide more information on the qemu official IRC channel
(lmr).
