Uwsgi segmentation error when using flask and python requests

Question

I start the dev uwsgi server using a jar and calling request.get causes a segmentation error in the uWSGI process.

Segmentation Error:

!!! uWSGI process 70490 got Segmentation Fault !!!

Running a snippet of python code directly from the command line without any problems.

I reinstalled uwsgi and that didn't seem to work. I do not really understand the intricacies of uWSGI configuration parameters. Is it possible there is something like this in my configuration file?
