Betternestedset talk - Sep 2007 - NoMethodError when using all_children_count on single-node set

Noob here. When I try to use methods such as
all_children_count (and other methods) on a set
consisting of a single node, I get the following
error:

NoMethodError: You have a nil object when you didn''t
expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.-
        from
./script/../config/../config/../vendor/plugins/betternestedset/lib/better_nested_set.rb:564:in
`all_children_count''
        from (irb):27

I get no such error if children are present. And
has_chidren? doesn''t produce the error.

Does anyone else see the same thing?

thanks,
Rich
