Fiona: Error opening geojson file

[klonuo]

I use fiona 1.7.7, and get this error while trying to read a file:

@klonuo this issue is related to #455 in that the GDAL error we want to see is hidden by a Fiona bug. #456 will fix the Fiona bug and let us see what the actual problem with your data and code is. I'm going to schedule a release with this fix in the next day or two.

@klonuo I'd be much obliged if you could try the new 1.7.8.
