Package: qemu Version: 2.5+dfsg-4+b1 Pleae have a look at already reported and fixed BUG here:
https://bugzilla.redhat.com/show_bug.cgi?id=1300209 Same error message is with debian-testing, haven't tested with 2.5+dfsg-5 yet, because fix is of date 2016-01-30 so I think it has not made it in. Thanks and best regards Uli
