It will, if you try to write multiple values to a unique property.

The problem comes if you make a non unique property, load multiple  
values, and then change the schema to be unique.

There is a MQL envelope parameter called 'uniqueness_failure':'soft'  
which was invented to address avh's concern.
if it runs across non unique data it will return only the first  
element and log a warning on our side.
