python-scipy is currently failing all debci tests in both unstable and 
testing.

I haven't marked it RC myself since I'm not 100% certain what the usual 
protocol is for marking the severity of debci test failures.  But as I 
understood it, debci test failures is considered RC under the final 
freeze which we're about to enter (but we're not quite in that deep 
freeze yet).

Hi Andreas, I may not have been clear.  What I mean at this point is to 
upload a small patch for scipy 1.1 to ignore the deprecation warnings 
(scipy 1.2 already does that).

If that doesn't help pass the debci tests then we can consider uploading 
scipy 1.2 instead.  But python-fluids and dipy FTBFS against scipy 1.2 
(a new version of dipy is available which presumeably fixes that)

Certainly please do unblock if the full freeze is already in place. But 
my intention was to first upload python-scipy 1.1 with a small patch, 
not 1.2 just yet.
