+1, Confirmed.

I removed from the DB the only self-referring relationship (FK to PK of the same table) I had added on the project, re-generated the ERD, saved it to a .pgerd file, and now the new file can be loaded without problems (*).

Interestingly enough, if I remove the relationship ONLY on the ERD (but not on the actual DB) and save the modified .pgerd file, the problem is still there.

(*) The problem with saving images #8424 remains, though. That's likely unrelated.
