Ah, great, now I see where the error happens. The reason seems to be
that `preview-gs-command' is nil. If you didn't set that explicitly,
then it seems there is neither "rungs", "mgs", "GSWIN32C.exe", nor "gs"
on your PATH.
Don't you have GhostScript installed? That's required by preview.
Bye,
Tassilo
