Mouse pointer dissapear in gdm

["edu gargiulo" <egargiulo+lists@gmail.com>]

After a fresh install and dist-upgrade to sid, the mouse pointer have
dissapeared.
The mouse is working, and I can click some objects in "blind" mode,
but I can't see the mouse arrow.
How can I fix it? I've installed lenny-amd64

regards,
