The problem seems to be in:
13 QNetworkConfigurationManager::~QNetworkConfigurationManager() X:\QtS60\src\network\bearer\qnetworkconfigmanager.cpp:233 0x0403ff2e
where code is:
QNetworkConfigurationManagerPrivate *priv = connManager();
priv->disablePolling();
And the priv is NULL:
priv 0x00000000 this 0x54589060
