Unhandled Exception in QTableView->setModel(QSqlTableModel)

Windows, Qt Creator 1.0.0, Qt 4.5.0

I'm creating a little SQL input form. In the main window constructor, I create a QSqlTableModel and when I try to associate it with a QTableView created in QDesigner I get the runtime error:

Unhandled exception at 0x00f8a5be in Forecast1.exe: 0xC0000005: Access violation reading location 0x00000004

The arrow in the following code is where it is occurring.

In running in the debugger traces it to the lines below, at (in qwidget.h line 144):

QWidgetPrivate *pd = parent->d_func();

is where it happens, when I step a message displayed is: ' stopped: "signal received" ' and the debugger will not go beyond the "Q_DECLARE_PRIVATE(QWidget)" line in the last section.

Thanks,

P.S., let me know if it would be better to paste the code in here instead of having them as attachments.
