Multiple ManyToManyField fields with same "to" reference tries to create duplicate tables

Revsion 257 added support for adding multiple ManyToManyField fields with the same "to" class on the same class. I've tried adding two fields where one has an explicit rel_name option but running "django-admin.py sql myapp" is showing two CREATE TABLE statements with the same table name.
I think I've tracked the problem down to the get_m2m_db_table method in the ManyToManyField class in core/meta.py but I don't understand the code base enough yet to try to fix it.
It looks like the code is returning the name as myapp_fromname_toname but I'd expect the name of the many-to-many table to be myapp_relname when the rel_name option is specified.
I'm using the MySQL database engine but I don't think that has any bearing on this problem.
