So, actually it's a problem with py-fiona. Works well after rebuilding and reinstalling py-fiona from sources, but I'm not sure if it just enough to bump py-fiona port revision to completely solve this problem.

I tried that and it still does not work for me.

But something strange is going on. If I import fiona first and then import geopandas, it works!

This appears to work now.
