Bug#880245: statsmodels

[Rebecca N. Palmer]

Is the subject line a leftover, or are you actually proposing to move 
0.9.0 from experimental to unstable (which is not generally allowed in 
soft freeze)?

The upstream fix for #880245 (the original reason given for wanting the 
new version) is supposedly

https://github.com/statsmodels/statsmodels/commit/f81cde31421288e669e859d0e798d843ca2ecabe

but I haven't tried it by itself.
