### Reproduced
I could not see this more than once.

Reproduce the crash by opening a note in the debug app, then start at app/src/main/res/layout/fragment_note_editor.xml line 52 and com.automattic.simplenote.widgets.SimplenoteEditText. Trace the constructor failure from NoteEditorFragment.onCreateView at line 427 and obtain the full underlying exception. Done means opening a note in debug no longer crashes.
