extraneous(?) autocomplete info

I'm getting a ton of (what I would call) extraneous autocomplete information in Ruby Netbeans.

For example, if I type the name of a model object and then type a period (whether I'm in a controller or a view), it shows a dizzying dropdown list of thousands of methods, including several hundred different versions of the "new" method (but no documentation - most method signatures are followed by "No comment found").

Has anyone encountered (and solved) this problem, if we agree that this is a problem? Could it be that I simply have access to all of those thousands of methods and so they must be reported by autocomplete?
