Hey, I have just installed the django-mptt lib, but i don't know how to get it to work :(

I have added

```
from mptt.models import MPTTModel

class Category(MPTTModel):
    slug = models.SlugField(max_length=200, unique=True)
    name = models.CharField(max_length=100)
    parent = models.ForeignKey('self', blank=True, null=True, related_name='child')

```

It that works fine

But when i go to the Django Admin page of my site i got an error:

TemplateDoesNotExist at /admin/search/category/

admin/mptt\_change\_list.html
