I'm getting the error: Exception Value: (1110, "Column 'about' specified twice")

As I was reviewing the Django error page, I noticed that the customizations the model User, seem to be appended to the List twice.

This seems to be happening here in django/db/model/base.py in base_save():

values = [(f, f.get_db_prep_save(raw and getattr(self, f.attname) or f.pre_save(self, True))) for f in meta.local_fields]

this is what Django error page shows values to be:

values = [(<django.db.models.fields.CharField object at 0xa78996c>, u'kallie'),  
(<django.db.models.fields.CharField object at 0xa7899cc>, ''),

Since this app is in Production, I can't figure out how to use pdb.set_trace() to see what's going on inside of save_base.

The customizations to User are:

    User.add_to_class('email_isvalid', models.BooleanField(default=False))  
    User.add_to_class('email_key', models.CharField(max_length=16, null=True))  
    User.add_to_class('reputation', models.PositiveIntegerField(default=1))  
    User.add_to_class('gravatar', models.CharField(max_length=32))  
    User.add_to_class('email_feeds', generic.GenericRelation(EmailFeed))  
    User.add_to_class('favorite_questions', models.ManyToManyField(Question, through=FavoriteQuestion, related_name='favorited_by'))                  
    User.add_to_class('badges', models.ManyToManyField(Badge, through=Award, related_name='awarded_to'))  
    User.add_to_class('gold', models.SmallIntegerField(default=0))  
    User.add_to_class('silver', models.SmallIntegerField(default=0))  
    User.add_to_class('bronze', models.SmallIntegerField(default=0))  
    User.add_to_class('questions_per_page', models.SmallIntegerField(choices=QUESTIONS_PER_PAGE_CHOICES, default=10))                             
    User.add_to_class('last_seen', models.DateTimeField(default=datetime.datetime.now))                     
    User.add_to_class('real_name', models.CharField(max_length=100, blank=True))  
    User.add_to_class('website', models.URLField(max_length=200, blank=True))  
    User.add_to_class('location', models.CharField(max_length=100, blank=True))  
    User.add_to_class('date_of_birth', models.DateField(null=True, blank=True))  
    User.add_to_class('about', models.TextField(blank=True))
