Comment 1 for bug 1410698

I confirm that behavior.
In first try stack is not deleted due to:

2015-01-21 11:52:25.153 23101 DEBUG heat.engine.stack [-] Context user_id doesn't match trustor, using stored context _delete_credentials /usr/lib/python2.7/site-packages/heat/engine/stack.py:904

However it deletes projects:

And just after this:

So I try to delete again and:
