3765	Exception when adding a new record in the admin form with related recordss	ross@…	Adrian Holovaty	"With this model:
{{{
from django.db import models

class Paper(models.Model):
    class Admin:
        pass

    title = models.CharField(maxlength=200)
    
    def __str__(paper):
        return paper.title
    
class Note(models.Model):
    paper = models.ForeignKey(Paper, edit_inline=models.STACKED, num_in_admin=1)
    text = models.TextField(""Comments"", core=True)

}}}

If I go the the admin site, add a new Paper, enter a title and leave the Note Comments field blank, when I press Save I get this exception:

The problem is that new_data.get() returns """", and then doing [0] throws the IndexError.

I can replicate this with Django 0.95.1 and svn (rev 4752).  I'm using sqlite3 as a database, Python 2.5 on Ubuntu Feisty Fawn."		closed	contrib.admin	dev		invalid			Unreviewed	1	0	1	1	0	0
