I tried with an empty data file but it's not enough to replicate this bug.

This is my test script:

-------------------------8<------------------------------------------------
import requests

url = 'https://contributors.debian.org/contributors/test_post'
files = {'data': open('test.json.xz', 'rb')}
payload = {'source': 'bugs.debian.org', 'data_compression': 'xz'}

if __name__ == '__main__':
    r = requests.post(url, files=files, data=payload)
    print(r.text)

Many thanks for the hint, I will also ask to upstream developers: they are 
very supportive so I hope we will have a solution soon.

This is really appreciated, thanks! I have already used it to wrote my test 
script. And I will use again for testing.

I have quite completed the packaging requests 2.8.1-1, but I'm waiting for the 
upload of python-urllib3 1.12-1: I'm sorry for the delay, but although I'm a 
DM since September, my usual sponsor had problems giving me upload permissions 
using dcut.

I will try your test case both with requests 2.7.0-3 and 2.8.1-1.

Kind regards,
