[Precise] nanny-admin-console preference tool doesn't launch

Dear Developers,

I installed nanny package my Ubuntu 12.04 system, and try launch Parental Control preference tool in System Tools>Administration submenu. After typing my admin password, the preference pane not displayed.
When I launch nanny-admin-console preference pane in GNOME terminal with sudo nanny-admin-console or gksu nanny-admin-console command, I see following error message, possible my oldest time installed Ubuntu 12.04 system have a problem:
/usr/lib/python2.7/dist-packages/nanny/client/common/Utils.py:33: GtkWarning: GtkSpinButton: setting an adjustment with non-zero page size is deprecated
  object.xml.add_from_file (main_ui_filename)
/usr/lib/python2.7/dist-packages/nanny/client/common/Utils.py:54: FutureWarning: This search is broken in 1.3 and earlier, and will be fixed in a future version. If you rely on the current behaviour, change it to './/object'
  for obj in xml.findall ('//object'):

Reproducation steps:
1. Install nanny package.
2. If you using GNOME3 fallback session, launch parental control preference tool in System Tools>Administration submenu. Alternative, you run gksu nanny-admin-console or sudo nanny-admin-console command in GNOME Terminal.

In quantal or 13.04 repository es the nanny package already not awailable, perhaps stopped the development this application.

I only want trying this application because I editing a hungarian tutorial book and not very need me the parental control feature, but possible other users need this function with have childrens.
