Hi all,
I've ran into a problem with Ferret on my rails app, and I don't
really have a clue about why. When running the unit tests, I get the
following error output:
> Exception raised:
> Class: <NoMethodError>
> Message: <"You have a nil object when you didn't expect it!\nThe

The problem seems to be caused by the following code in acts_as_ferret:
@sub_readers.each { |r| return false unless r.latest? }
which, in turn, causes a NoMethodError because @segment_infos is nil.
The problem (or, at least, the symptom) goes away when I add a rescue
clause inside the block that gets passed to @sub_readers.each, but it
feels like a bad way of solving it. Anyone who knows why this happens
in the first place? And what should I do to avoid it?
