SuperTabNavigator index out of bounds

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create SuperTabNavigator (id=m_viewArea) and add 2 or more tabs
2. execute the following code:

while (m_viewArea.getChildren().length > 0) {
  m_viewArea.removeChild(m_viewArea.selectedChild as DisplayObject);
}

What is the expected output? What do you see instead?
After all tabs are closed an error occures (index out of bounds...)

There is a simple solution:
1. to the SuperTabNavigator.as, function ensureTabIsVisible add code:

if (this.selectedIndex < 0) {
  return;
}
