Summary

Travis fails when running test_provenance (and 3 others), all pythons.

Actual behavior

see travis output for more details:
https://travis-ci.org/djarecka/nipype/jobs/198015225

Expected behavior

How to replicate the behavior

don't know how to replicate outside travis

[mgxd]

ran into this error in #1794 as well, adding icu directly to Travis's conda install seemed to fix it but I don't know if this is the best way to go

[djarecka]

@mgxd - I also found that people add icu to conda, I don't have any other idea.

[djarecka]

@mgxd : so won't create any new PR, if yours includes it.

[mgxd]

I believe this is fixed with #1794, but we should monitor this

[mgxd]

this is still present despite adding icu

[mgxd]

closing this for now after #1808
