An extenstion method for a WPF control is causing an StackOverflowException

Here's my extension method:

public static void SetThreadSafeProperty<T>(this System.Windows.FrameworkElement control, Expression<Func<T>> property, T value)
{
    if (control.Dispatcher.CheckAccess())
    {
        var del = new SetThreadSafePropertyDelegate<T>(SetThreadSafeProperty);
        control.Dispatcher.Invoke(del, control, property, value);
    }
    else
    {
        PropertyInfo propertyInfo = GetPropertyInfo(property);
        if (propertyInfo != null)
        {
            propertyInfo.SetValue(control, value, null);
        }
    }
}

And here's how I'm calling it:

tbManufacturer.SetThreadSafeProperty(() => tbManufacturer.Text, "test");

After debugging it, it looks like it gets stuck in an infinite loop. CheckAcess() is true and it creates the deletegate just fine and invokes correctly. But it keeps going and going and eventually fails.

Any ideas on why this might be happening?
