*bump*
I have tried a similar example from the Android site:
http://code.google.com/android/samples/NotePad/index.html
Which causes the same error when you manage to switch view from
landscape to portrait or otherwise cause onDestroy to be called just
as the ListView is being populated with data, thus causing this
exception:
