What do you mean by "stray"? Without a "%key:" line?

My guess is that G_parser() dereferences the "key" field without
checking that it is non-NULL.

I suspect there are probably other ways in which you can construct
options which G_parser() won't like. I'm not sure how practical it is
to fix this in g.parser rather than G_parser() itself.
