The content of the adapter has changed but ListView did not receive a notification - With AsyncTask

I am using AsyncTask to set my items and stuff, in the postExecute i call a synchronized Method where i do this

mAllResultsAdapter.setItems(mAllResultsItem);
mAllResultsAdapter.notifyDataSetChanged();
mListView.invalidate();
mListView.requestLayout();

Most of the time if I dowload new data and update my listview/adapter it simply works, and pretty good to. But somehow it crashes sometime, can anyone assist me with this issue.

heres my crash log.
