It looks like an issue with altering the field `'name'` in the second migration. When I comment out the `migrations.AlterField` for `'name'`, the migrations work. I'm using Django 1.9.1, Python 2.7.6, and PostgreSQL 9.3. Here's the failure traceback: {{{ Traceback (most recent call last): File ""./manage.py"", line 12, in execute_from_command_line(sys.argv) File
