Sorry, there was some confusion here. The proposed fix for this bug was removed since it failed. Unfortunately the bug# had to stay in the changelog so this bug was updated suggesting there was a new fix for it. Rather libvirt 1.2.2-0ubuntu13.1.12 drops the proposed patchset for this bug, and the proposed qemu version will be deleted or simply superseded without this fix.

(So comment #15 was a mistake)
