manage.py loaddata stopped working on Django 1.6b2

Hello,

I have a script for loading fixtures that always worked in Django and it suddenly stopped working on Django 1.6b2. It works on 1.5.1, 1.5.2 and 1.6b1.

### Create an app called appname and a folder called fixtures with a file groups.yaml like this:

- fields:
    name: Group1
    permissions: []
  model: auth.group
  pk: 1
- fields:
    name: Group2
    permissions: []
  model: auth.group
  pk: 2
- fields:
    name: Group3
    permissions: []
  model: auth.group
  pk: 3

### Try run on terminal
python manage.py loaddata appname/fixtures/groups.yaml

### Output for Django 1.6b2
.../local/lib/python2.7/site-packages/django/core/management/commands/loaddata.py:218: UserWarning: No fixture named 'appname/fixtures/groups' found.

warnings.warn("No fixture named '%s' found." % fixture_name)

Installed 0 object(s) from 0 fixture(s)

(test was made using PostgreSQL with psycopg2 2.5.1 - I didn't had time to test on other dbs)

The major refactoring in 51aa000378c00a442273f01142acdebc94dec68d may have broken loading fixtures from an absolute path, but it was before 1.6b1. Are you positive it still works in 1.6b1?

It would be extremely helpful if you could bisect to find the commit that introduced the regression.

I am sorry! I just noticed this error now (testing in 1.6). I am sure it works on 1.5.1 and 1.5.2 not in 1.6b1. I will make the test again in beta 1.

Right. I must have broken loading fixtures from an absolute path — the third option mentioned here: ​https://docs.djangoproject.com/en/dev/howto/initial-data/#where-django-finds-fixture-files

Testing done, it doesn't work in 1.6b1 either. I am sorry again.

No, absolute paths work as intended:

./manage.py loaddata `pwd`/appname/fixtures/groups
Installed 3 object(s) from 1 fixture(s)

The issue is relative paths, which aren't documented to work, though it would make sense that they do, I'll see what I can do.
