v1.2.2b4

This includes an additional fix that (due to changes on the on commit handling on CRUDEvent creation, if there was an error and the logger tried to log it, it was possible that instance's repr/str would have included something that was already deleted (this is a consumer level issue), so now we will try/except on the logger and pass if we have an error (not wonderful for now, but easier to just do that and get the release out).
