Unfortunately, the patch which dispatches errors from qemu-agent-command has been submitted after the 1.0.6 release:

    libvirt-qemu: Dispatch errors from virDomainQemuAgentCommand()

    The original implementation didn't follow the established pattern and
    did not dispatch errors in case of failure.

So if you could try out building the libvirt from git and get the real error.
Or if you want to use the 1.0.6 release, you'll find the error message in the libvirtd log.
