What is this error?

It is caused by {{{contenttypes.name}}}, see SO:
http://stackoverflow.com/questions/10855978/heroku-and-django-value-too-long-for-type-character-varying50

Easily replicated:

{{{
class MyModel(models.Model):
    class Meta:
        verbose_name = ""soem ridiculously long verbose name that is out of control""
}}}
