Comment 2 for bug 380862

I think what might be really cool would be implementing this without adding any extra interface. Instead of requiring QA people to realize the common misfiling and link the projects/packages themselves, Launchpad could set up the duplicate-finding link from X to Y automatically whenever more than N% of bug reports filed under X get marked as duplicates of bug reports filed under Y. (You'd need to wait until X had a decent number of bug reports, 200 or so, so that a random blip didn't send the proportion over the threshold.)
