How about wrapping things in a try/catch to see what the exception message says? I do something similar, here's what works for me:

try {

  final TabHost tabHost = getTabHost();

  tabHost.addTab(tabHost.newTabSpec("tab1")
         .setIndicator(mContext.getString(R.string.tab_label_game), res.getDrawable(R.drawable.ic_tab_state))
         .setContent(new Intent(this, ActivitySettingsStates.class)));

  tabHost.addTab(tabHost.newTabSpec("tab2")
         .setIndicator(mContext.getString(R.string.tab_label_alerts), res.getDrawable(R.drawable.ic_tab_alerts))
         .setContent(new Intent(this, ActivitySettingsAlerts.class)));
}
catch (Exception ex) {
  if (DEBUG) Log.e(TAG, PROC + ": Exception occurred: " + ex.toString());
}
