The function that detects this was inadvertently disabled (it was
only active for old versions of the compiler).  That's fixed now.

The function `nil_method' is called by the Objective C runtime
whenever messages are sent to nil.  For example if you add this to
your model, you'll get warning messages for messages sent to nil.

id
nil_method (id receiver, SEL op, ...)
{
  raiseEvent (WarningMessage, "`%s' was sent to nil\n", sel_get_name (op));
  return nil;
}
