The number of crashes has dropped dramatically with the property (dvv_enabled) updated. Now, I'm periodically seeing crash messages like:

The crash report is for the same reason, the 3rd argument to riak_object:merge_contents/3 is <<"false">> when it should be the atom 'false'.

Is that crash report from _after_ you updated the bucket properties?
