RuntimeError: original source dist cannot contain .pyc files

Trying to convert PIP packages into Debian packages using python-stdeb (for maintainability purposes). Having scripts and mechanism to do it, which works perfectly fine. It converts any PIP package into debian except for flasgger version 0.6.0+ (so 0.5.14 and every version below getting converted just fine):

Again this happens only of Flasgger version >= 0.6.0.

Was something changed severely between 0.5.14 and 0.6.0 that could cause the problem with PYC files?

Maybe this can be used in the MANIFEST file:

global-exclude pat1 pat2 …	exclude all files anywhere in the source tree matching — & any of the listed patterns

something like (if I understand it correctly):

global-exclude __pycache__

or maybe the problem is https://github.com/rochacbruno/flasgger/blob/fe53c1dbed31e0ecd0752f068f03b09f4183458f/setup.py#L44
