Worked for me on an installed Debian, inside Xfce with xfce4-terminal.

1) What version of Python are you running?
2) Are you running inside some kind of graphical environment?
3) Do you have any sort of permissions/environment change happening? I
get an error like that if I try "sudo python" without any sort of
guard.
