From Allakhazam :-

This little gem of info really should be noted in the quest information, but it is possible for you to receive a Bad Regurgitonic from Kimble Nogflop. I spent weeks trying to feed Frostbite a regurgitonic that he just kept telling me was something he didn't want. I cast Identify on it, and it's lore info said: Bad Regurgitonic. I destroyed it and got another one, which worked perfectly fine.

So, before you start to think that something about Frostbite is broken, check to see if you've got a bad regurgitonic...chances are that is your problem.
