failed to delete migrated projects

[changsijay]

I use version 1.0.1 jar and migrated some projects from redmine.
While I want to delete those projects from django /admin/projects/project/, it resulted in internal server error(500) as below error:

In /admin/projects/project/, project id=8 is the migrated project. It still there now.

ERROR:2016-08-26 11:18:46,917: Internal Server Error: /admin/projects/project/
Traceback (most recent call last):
  File "/home/devops/.virtualenvs/taiga/lib/python3.5/site-packages/django/db/backends/base/base.py", line 211, in _commit

The above exception was the direct cause of the following exception:

oh, sorry, I found it is not migrator issue.
It failed when I tried to delete project, even those from python manage.py sample_data
