The most you can do is handle NavigationFailed:

browser.NavigationFailed += new System.Windows.Navigation.NavigationFailedEventHandler(browser_NavigationFailed);

void browser_NavigationFailed(object sender, System.Windows.Navigation.NavigationFailedEventArgs e)
{
    Debug.WriteLine(e.Exception);
}
