Hmmm... that is a problem. Quoting behaviour should be correct if the 
value needs quoting - so it sounds like there is a bug somewhere in the 
quoting logic. It will be deterministic - so it should be possible to 
reproduce.

If you set the value to be the tuple instead of the repr of the tuple it 
will get written out as a list however.
