The comment just before the assert() explains what it tries to catch:

// Make sure that the number of columns in the result returned by
// the database matches the number that we expect. A common cause
// of this assertion is a native view with a number of data members
// not matching the number of columns in the SELECT-list.

Though it seems like you are loading an object so this can't be that.

Yes, that would be very helpful.
