Address boundary error on POST QHttpMultiPart

[Šimon Leitgeb]

Hello,
I'm currently working on an application that sends some requests using
PyQt, but multipart formdata post requests are giving me trouble.

Get requests and simple post requests (with just binary data as body) work
without any problems, but requests that contain QHttpMultiPart as body
crash Python with the following:
fish: Job 1, 'pipenv run python post.py' terminated by signal SIGSEGV
(Address boundary error)

I'm using PyQt5 with Python 3.11.5, but the same issue occurs in PyQt6 as
well.
You can find a minimal example attached, if anyone would like to test this
for themselves.

Any ideas why this program crashes?

All the best,
Simon Leitgeb
