GitReader.Repository.Factory.OpenStructureAsync throws "Offset and length were out of bounds"

When opening the repository https://github.com/ethereum/solc-bin using GitReader.Repository.Factory.OpenStructureAsync I get the following exception:

System.ArgumentException: Offset and length were out of bounds for the array or count is greater than the number of elements from index to the end of the source collection.
