#23031: Django 1.7.x test failing for application with migrations and initial
data
----------------------------+----------------------
Reporter: linovia | Owner: nobody

Component: Migrations | Version: 1.7-rc-1

----------------------------+----------------------
It seems commit 0dd737a719cfbd3bc11ff6f2b90161883fcebea0 introduced a
regression in the following case:
- the application has migrations
- the application has initial_data
With this configuration Django will crash before any test is run.
This is caused by the initial_data being loaded at the end of the flush
while the migrations did not create the associated tables yet:
