There's lotsa chatter about this issue here, but here's the Reader's Digest version of the "permanent fix".
Since many people have had their plastic tanks replaced at least once, Ducati will supposedly have a metal one available in the next few months. Since the issue is considered one that's covered by Ducati's 5 year emissions system warranty, you won't have to worry about getting a spreading tank warrantied if the regular 2 year warranty is up.
It seems that most dealers won't replace one they believe can be fixed by shimming, so how easy it is to warranty one is largely dependent on the dealer.
Based on the most popular theory that ethanol gas is the culprit, some here have lined their tanks to prevent spreading, and there's plenty of info here on the details of that. Other's have recently been using additives designed to prevent the ethanol from working its alleged evil.
Also, it's important to remember that not everyone has had a spreading tank, although I think those that have outnumber those of us who haven't by 2 to 1 or more.
