[Pkg-libvirt-maintainers] Bug#1072723: libvirt0: qemu:///session not connected after login

This does not work for me ; it works only if a prepend sudo ; root is
the only user that has access to qemu:///session  which is a paradox
because users like me are using qemu:///session (for trying) to avoid
unwanted privileged access.

virsh -c qemu:///session connect
error: cannot connect to hypervisor
error: cannot receive data : connection reset by peer

I obtain this message with virt-manager :

Unable to connect to libvirt qemu:///session.

Cannot receive data : Connection reset by peer

Libvirt URI is: qemu:///session

libvirt.libvirtError: Cannot receive data : Connection reset by peer

The wiki of libvirt treats some  "cannot connect to hypervisor" common
causes, but there's no reference to connection reset by peer.
