I would think that you should get an error in 3.2 about a missing 
collator (or mysterious Transaction error) when updating and/or 
accessing the index ...

It would be useful for me to see the full stack from the 3.3 Transaction 
error (or at least more context about what was actually going on when 
the error occurred) ... it is likely that the transaction error was 
triggered by an earlier error ... and whatever operation you were doing 
in 3.3 should trigger a similar problem in 3.2, since collator's are 
required in 3.2 as well ...
