The security groups stack trace is just a side effect of cells falling over in a really low level way (this is what's before and after the trace).

Thanks for looking into this.

I was looking at this run - 
  (which was on my requirements update)

There is definitely a screen-n-cell.txt.gz in the log directory there, 
which is where I got that from. We pick up all the screen-n-* files, but 
you'll only see this on gate-tempest-devstack-vm-cells-full runs.
