Hello List,

I have a crash with M3 that I didn't have with M2. I updated the
models (I have two models), cleaned everything, rebuilt.

Upon first commit I get the following crash.

I am not doing anything special. Just inserting a record then saving.
Several queries worked perfectly well before that point in the
application.
