Are the dropouts properly aligned?

I'd check the alignment of not just the dropouts but the whole rear triangle. Sheldon Brown's string method will do the trick.

I checked the rear stays doing the string from point to point and around the headtube, that was cool.

I also did it around the bridge, that was cool...

Put a straight edge along the stays, cool there.

The drop outs are the culprit. Working them right now, got it to within 1/8" side to side.

Even if the stays are symmetric, if the dropout slots aren't the exact same height above the ground the wheel will be tilted to one side. The result is offset on the top of the wheel but not on the front where you typically look for wheel alignment. You can pretend to fix it by re-dishing the wheel or by tweaking the stays until the top of the wheel is centered, then correct the alignment of the front of the wheel with the dropout stop screws. But it still leaves the wheel slightly non-vertical.

I don't know how common this problem is. I would guess it is rare on decent bikes. I've seen one frame where that the only way to explain how the rear wheel fit.
