Relationship on Nodereferrer causes duplicates in Views3

Issue Summary

Hi,

I'm using a relationship on a 'Nodereferrer' field to build a listing of 'Views_gallery' galleries with an image thumbnail; in Views2, the "distinct" operator worked so that each gallery node became one record with one image from the gallery.

In Views3 this seems to have changed fundamentally; now I get 77 records for a gallery with 77 images (instead of one). I tried to target one item from the nodereferrer by choosing a delta (e.g. "1") which always results in 0 items.

I'm pretty confident that the duplicates are caused by nodereferrer because they immediately disappear as soon as I delete the relationship ;) However, this removes the images thumbnails as well, so I believe that here is some kind of issue that shoould be fixed, if possible.

Please feel free to ask about details of my use case if necessary; it's a bit complicated to describe, but I'll try my best.

Thanks!
