Is it PTVS code base? The bug was fixed here. The code above is trying to open directory as a file. See https://github.com/Microsoft/python-language-server/pull/86/files. This is why AstTypeStubPaths tests fail.

Closing in favor of #32. If urgent, pick the https://github.com/Microsoft/python-language-server/pull/86/files
