Idina herself was nervous about the "nude" scene (listen to her Chatterbox interview sometime), so don't jump directly to the "I'll lose so much respect for her" thing. Many actors do it, and it's for the sake of a role and their art.
The scene wasn't smutty (and you didn't really see THAT much) -- There was a specific film effect done that distorted that image, making it look more like a painting rather than real life... It went in and out of this effect during the first few bits of her scenes (as well as the short nude scene), and it looked something like this (the effect):

Just don't make judgments based on someone showing their breasts. It's done... ALL THE TIME. hardly worth getting huffy about. Plus, Idina has nice breasts, so where's the problem?
