Research direction

Start at MainFragment.java:1420 in goBack(), reached from MainActivity.onBackPressed(), and inspect the substring operation that raises StringIndexOutOfBoundsException with index -9. Reproduce the reported back-navigation action if possible; done means pressing back through the affected state no longer crashes the application.
