(Note: the file was a prediction with only one promoter, and hence
no sequence predicted at all. The parser crashed on this one, as
well as complaining about a number of undefined values when using
-w.)

Brian, this was obviously a bug. I fixed it on main trunk as well
as 0.7.x branch. I still have to add the according test for it.
(BTW feel free to add this yourself to the Genscan tests if you
feel up to it.)
