2500	[patch] admin popup window stays open after adding and saving an item that has a primary_key=True field	Gary Wilson <gary.wilson@…>	Adrian Holovaty	"I have the models:

{{{
#!python
class Semester(models.Model):
    name = models.CharField(maxlength=20, primary_key=True)

class Course(models.Model):
    number = models.CharField('course number', maxlength=6)
    title = models.CharField('course title', maxlength=100)
    semester = models.ForeignKey(Semester)
    year = models.PositiveIntegerField()
}}}

Steps to reproduce:
 1. In the admin, click Courses.
 1. Click add course.
 1. Click plus next to Semester dropdown.
 1. Fill in semester name.
 1. Click save.

What happens:
 * The add semester popup window goes blank.
 * The add semester popup window does not close itself and must be closed manually.
 * The new semester entry does get created in the database.
 * The semester dropdown in the add course form does not get populated with the newly created semester like it should."	defect	closed	contrib.admin	dev	normal	fixed		gary.wilson@…	Unreviewed	1	0	0	0	0	0
