Play loop, change loop-location, undo. Undo calls Locations::set_state, takes a writer-lock, and calls Location::set_state which emits a Changed signal. This triggers Editor::location_changed, and if loop-location changed while looping, update_loop_range_view() queries the loop location, taking a reader-lock. This leads to a recursive lock, RWLock::ReaderLock after a RWLock::WriterLock does not cause a deadlock, however releasing the ReaderLock effectively also unlocks the WriterLock. This leads to a deadlock next time a writer-lock is acquired.
