I think something is broken in the terminal emulator. You are able to
launch gnome-terminal itself (presumably from the menu or the Alt-F2
dialog), but then something within that environment is causing your
problem. I suggest you try launching from xterm. If it works there,
compare the output of the 'env' command in the two terminals.
