Validate_uniqueness_of builds queries with IS NULL when valu

Hi people,

Ever since RC 5 (including 1.0) my unit tests that test for inserting
duplicate entries fail and throw errors. Each of them implements
validate_uniqueness_of to prevent duplicates. While I also put in a
ticket for this, I’m wondering if this is actually a defect or maybe
intended behaviour afterall. If so, I won’t apply the patch again and
look for another solution.

Tell me, should I patch it? :wink:
