Issue:

We got a coredump with the latest version 0.3.10 (build 2): https://travis-ci.com/github/lldelisle/pyGenomeTracks/jobs/362129644#L974

libopenblas-0.3.9 seems to work for us. Both versions (also 0.3.10-openmp_h709eae2_2) seems to cause the segfault.

I can try to revert this PR. Should we pull our packages?

I'd rather not. Pulling latest will result in segfaults for others

I think the impact is rather big of this issue and its not clear how long it will take to fix it upstream. Reverting is not as easy. I will have time today in the evening to try again.
