QSqlQueryModel::setQuery - SIGSEGV

[onamatic]

Thank you for your suggestion wysota.

I extracted the relevant bits of code and tested this threadless morsel:

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL");
	db.setHostName("localhost");
	db.setDatabaseName("mythconverg");
	bool trashok;
	db.setPort(QString("3306").toInt(&trashok));
	db.setUserName("mythtv");
	db.setPassword("mythtv");
	bool ok = db.open();
	if (ok) qDebug() << "Open OK";
	else qDebug() << "Open failed";
	QSqlQueryModel amodel;
	amodel.setQuery("SELECT sourceid FROM videosource"); //BANG! SIGSEGV
	...
}

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL");
	db.setHostName("localhost");
	db.setDatabaseName("mythconverg");
	bool trashok;
	db.setPort(QString("3306").toInt(&trashok));
	db.setUserName("mythtv");
	db.setPassword("mythtv");
	bool ok = db.open();
	if (ok) qDebug() << "Open OK";
	else qDebug() << "Open failed";
	QSqlQueryModel amodel;
	amodel.setQuery("SELECT sourceid FROM videosource"); //BANG! SIGSEGV
	...
}

So then I reverted from the Qt 4.5.0 snapshot to 4.4.3. and setQuery then worked as advertised. I will try picking up the latest 4.5 snapshot tomorrow to see if that has fixed anything.
