Now that I actually check with a non-relation object, I see pretty much the same error. So probably if instead of some narrow bug fix what we need is some general solution for all object types. I know this has been discussed a number of times ... Anyway I see now that we should not consider this a backpatchable bug fix, and I'm not doing the coding either, at least not now.
