QCoreApplication::postEvent: Unexpected null receiver

[Kumosan]

I am having the exact same Problem also on XP QT 4.2.2 OpenSource.
Anyone knows a solution to this issue or what i might be doing wrong?

You probably use either one of below methods directly or indirectly and *receiver is a 0 pointer.

QCoreApplication::postEvent ( QObject * receiver, QEvent * event )
QCoreApplication::sendEvent ( QObject * receiver, QEvent * event )
