We believe that we have fixed the recurring crash in version 2.3.3 with the tracing and references menu, and are testing a build for release. Update 2.3.4 should be available as soon as we are certain that it works correctly and it has been approved by the App Store (which means that we don't have a date yet, we just wanted to let you know that it is definitely getting fixed!).

The details and crash reports sent in by users have been extremely helpful in locating the cause of the crash, and we are sorry that it took so long to fix.
