I think d41d8cd98f00b204e9800998ecf8427e is the md5 sum of "nothing", e.g. md5 reverse will get you a zero-length stream of characters.

(granted this is entirely without looking at the data) but my guess is that they MD5 hashed whatever was in that apartment_id column and if it was empty it spat out d41d8cd98f00b204e9800998ecf8427e

>Ah yes, I recognise that particular md5 hash value from memory.

Excellent, I certainly know I am reading HN.

Yep:

 touch null ~  md5sum null d41d8cd98f00b204e9800998ecf8427e null

Wow! I have memorized some bizarre things before, but I don't think I ever went that far to recognize an md5 hash.
