I went for the Indy, hope its that nice!
I may have missed it, but I didn't see anyone respond to your post.
The answer is yes, be concerned. You are seeing the inseam stitching, which essentially means that the shoe is coming apart at the foundation. The inseam is the stitching that holds the welt, upper and insole together as a cohesive unit. If you continue to wear them, they will begin to distort, because they are flexing in the zone that they are coming loose in. The leather will be able to move freely to the side along the gap that you see, which will change the width of the uppers at the ball of your foot. The only proper way to fix that would be to have Alden re-last them on the original last, and have a new welt sewn on. Essentially, a recrafting done at the factory. As for who to contact (Kathy or Alden directly), it's probably inconsequential.
Alden seems to be having some issues with their inseaming of late. Your picture is one of a handful that have been posted over the last year or so. This shouldn't occur as frequently as it seems to be lately.
