line 2460 of qobject.cpp
in QObject::connect

QMetaMethod rmethod = rmeta->method(method_index);
if ( receiver != this  && rmethod.access() == Private)
	qWarning("cannot connect to a private slot");

but wait...  QObject::connect is static ...  so there is no this :-(
(but i'm sure this can be worked around.)
