Throws errors when trying to type the name of an `#include`d header

Here are the steps:

Create a new file (touch derp.c)
Edit the file (nvim derp.c)
Type the following: #include <
Once I start typing the name of the header (e.g. stdio.h) deoplete throws the following errors:

[deoplete] Traceback (most recent call last):

[deoplete] TypeError: 'generator' object is not subscriptable

This happens every time. Any idea?
