* 2013-03-18 - cketti
*
* Work around a bug in ListView (?) that leads to a crash deep inside the
* framework code.
* I didn't track down the exact cause of this. My best guess is that we change
* the data (remove items) while the ListView isn't visible. Probably because
* the view is hidden, layoutChildren() is never called and when this method
* runs the layout contains more item views than the adapter contains elements
* and bad things(tm) happen.
