Admin error when using extra fields on many-to-many relationships

I have created a models similar to the one in the docs. Previously the admin was working ok, but when I changed the model to include extra fields in the m2m relationship, the admin broke.

The models code:

class Coach(models.Model):
    user = models.OneToOneField(User)
    customers = models.ManyToManyField(User, related_name = 'customers', through='CustomerCoach')
class CustomerCoach(models.Model):
    user = models.ForeignKey(user)
    coach = models.ForeignKey(Coach)
    date_joined = models.DateTimeField()

The admin code:

class CustomersCoachAdmin(admin.ModelAdmin):
    pass, CustomerCoach)

I get this error:

'MediaDefiningClass' object is not iterable

I'm having this problem not only in the admin but in all the site usign this models now.

I have no idea what's going on.
