I'm not blaming Joe, I did a little research (after the fact) and it seems that this cracking is not an isolated issue with these rims. The front is nearly as pristine as the day I got them.....

Cracks can happen with any rim, and some are more prone to it than others. I haven't seen a problem with DT double eyelet rims until your picture. At least you got 13k miles out of them. The single eyelet rims are much more prone to cracks. I have seen many Shimano factory wheels with eyelet cracks on the rear drive-side. It looks like that is a nice wheel with a 240S hub. You can have the rim replaced with the same or alternate rim. If using the same rim you can reuse the spokes. You can also replace it with a TK540 rim without replacing the spokes which is a much stronger rim and looks almost the same except that it is wider.
