Description
This breaks if a ManyToMany field is specified as readonly.
This is because the contents() function that is called in the fieldset.html template tries to display the value of the field but gets a ValueError if it is a ManyToManyField because they can't be used: "[Model name] instance needs to have a primary key value before a many-to-many relationship can be used"
Just need to add ValueError to the catch as seen in the patch I attached, called catch_value_error.diff.
Hope it gets merged before beta 2.
