gnopernicus and gnome-mag

["mooncar libero it" <mooncar libero it>]

Hi!
I installed gnopernicus with gnome-mag and festival on my Kanotix, with apt-get. Gnopernicus is 0.9.19 version and gnome-mag 0.12.2. I have 2 problems:
1- gnopernicus speaks when I run it as a common user, but it don't speak if I logged in as root. It tells me 'speech unavailable'
2- gnome-mag don't works. I see a black square in the centre of the screen, and not magnification
Has someone already had these problems?
thanks
