Comment (by Simon Charette):
I'm pretty sure that's a bug in the MSSQL server backend used by the
reporter here.
MSSQL server diverges from the SQL standard by disallowing multiple `NULL`
values in column with a `UNIQUE` index. The backend should make sure to
create conditional indexes excluding `NULL` columns for fields marked
`null=True`.
