Description:

When I'm trying to create new VM with "Graphics: VNC", I get:

Error adding device: internal error unknown graphics device type '<gi.overrides.Gtk.TreeModelRow object at 0x7fab2ac43650>'

Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/addhardware.py", line 1308, in add_device

libvirtError: internal error unknown graphics device type '<gi.overrides.Gtk.TreeModelRow object at 0x7fab2ac43650>'

Additional info:
* package version(s) virt-manager 1.0.1-1
* remote system is Ubuntu 12.04. I _can_ do the same without any problems, connecting from another Ubuntu to the same server
* remote libvirt version is 0.9.8
* virt-manager 0.9.1 (from Ubuntu) works fine.


Steps to reproduce:
1) connect in Virtual Manager to remote Ubuntu 12.04 (qemu+ssh)
2.1) create/import VM with display type "VNC"
or
2.2) try to change display type from Spice to VNC
or
2.3) try to add VNC display to existing VM without display of any type.
