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
