Once you've proved it's the frame and not the wheel the fix is just to file the top of one of the dropouts a bit to rotate the wheel. You only need to remove a very small amount of material as the wheel multiplies the error by about 5.
I did exactly this on a Dahon fork. If the wheel mounted on reverse exhibits the same problem, it's a frame issue.
