Files uploaded using chromedriver get content_type 'application/octet-stream'

[siegcollado]

Meta -

OS: OSX

Selenium Version: 2.51.0

Browser: Google Chrome

Browser Version: 50.0.2661.94 (64-bit)
Chromedriver Version: 2.21.371459

Expected Behavior -

CSV files inputted to the file input field (using send_keys) should have their content_type text/csv

Actual Behavior -

They are of the content type application/octet-stream, so if the field is validated to accept only certain types (text/csv' or 'application/vnd.ms-excel') in my case, the file will fail to upload

Steps to reproduce -

1. Use selenium to navigate to a page that has an input field of the type file
2. use send_keys to fill out the input field with the path to the file
3. Verify the content_type of the uploaded file

I can provide a more detailed example if needed.

I am also looking for a workaround for this issue.
