Pillow error at trying to run django server

Hi,

I've created a virtualenv and Installed a markdown utility that requires Pillow. In production I get all to work but in the server I get this error:

Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x7fc23dddd730>

I made sure to run the script using python3 as is the version I selected when creating the virtualenv.
