I got a bunch of identical exceptions from a BlackBerry Z10 device using the Android Runtime 4.3. Whenever the user edits an EditText that already contains a text, the app crashes. Editing an empty EditText works fine. I don't own a BlackBerry device, so I'm unable to verify the crash.
Does anybody have an idea what happens here and how to solve or workaround the problem?
Here comes the stack trace:

Update Oct 31, 2014:
The evaluation revealed that the app doesn't crash when
- the EditText is empty or
- the EditText contains a text AND "selectAllOnFocus" is set AND the user starts typing, i.e. overwrites the existing text.
The app crashes when
- the EditText contains a text AND "selectAllOnFocus" isn't set or
- the EditText contains a text AND "selectAllOnFocus" is set AND the user positions the cursor inside the EditText (without overwriting the text before).
