After upgrading to virt-manager-1.4.0.2, I am unable to open details.

Attempting to open details fails with the following error message

Error launching details: 

Errore nell'avvio dei dettagli: 'nome-mv'

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/engine.py", line 820, in _show_vm_helper
    details = self._get_details_dialog(uri, vm.get_connkey())
  File "/usr/share/virt-manager/virtManager/engine.py", line 798, in _get_details_dialog
    obj = vmmDetails(conn.get_vm(connkey))
  File "/usr/share/virt-manager/virtManager/details.py", line 363, in __init__
    self.console = vmmConsolePages(self.vm, self.builder, self.topwin)
  File "/usr/share/virt-manager/virtManager/console.py", line 128, in __init__
    self._change_title()
  File "/usr/share/virt-manager/virtManager/console.py", line 291, in _change_title
    "connection-name": self.vm.conn.get_pretty_desc(),
KeyError: 'nome-mv'

Downgrading to 1..3.2-4 fixes this issue.
