I have a PreferenceActivity (TabTabHostPreferences) which is a tab in
TabActivity B (InnerTabActivity) which is a tab in TabActivity A
(TabTabPref). I admit its a bit convoluted but its design feels a
natural for my project. I am getting the error, listed below, when I
try to open a EditTextPreference in my TabTabHostPreferences. The
error occurs before the dialog appears. I have also included my
TabActivites for completeness.
