Also thanks for the feedback, I guess. Now I have reason to believe that this probably is an issue with all of my similar projects, which I couldn't have noticed, due to a complete lack of someone telling me.

Yeah, I was lazy and used the standard-exporter. (deadline was 5AM around here, and honestly - I threw all the modules I had built together, and disabled functions until it stopped crashing).
That error is curious too- 3.5 shouldn't even be a dependency.

I'll package it properly, once I'm at my machine again.

441MB... So why exactly did you include every python library in existance as well as blender? It doesn't even run:

./veelancer: error while loading shared libraries: libpython3.5m.so.1.0: cannot open shared object file: No such file or directory
