IOError when opening metadata schema

[LondonAppDev]

I am trying to harvest from a CSW endpoint with the following custom configuration:

{"validator_profiles":["gemini2"]}

I am getting the following IOError exception during the fetch stage:

Traceback (most recent call last):

IOError: [Errno 2] No such file or directory: 'validation/xml/gemini2/gemini2-schematron-20110906-v1.2.sch'

I have checked and the validation/xml/gemini2/gemini2-schematron-20110906-v1.2.sch file exists and has read permissions for all users.

I'm interested to know if anyone else is experiencing the same issue?

This is fixed with #176
