qtodotxt / PyQt5 dumps core

Running the test.sh script below dumps core on various pcs running both fedora 40 and 41:

test.sh: (beware it destroys your ./tmp and your pip cache)

cat /etc/os-release
python --version
which python
md5sum $(which python) 

rm -rf ./tmp
mkdir -p ./tmp
cd ./tmp
mkdir -p venv
python -m venv venv
. ./venv/bin/activate
pip cache purge
pip install -r ../piplibraries.txt
qtodotxt

where piplibraries.txt reads:

PyQt5==5.15.11
PyQt5-Qt5==5.15.15
PyQt5_sip==12.15.0
python-dateutil==2.9.0.post0
qtodotxt==1.9.0
six==1.16.0

The stdout of the script (on fedora 41) reads:

and stderr:

test.sh: line 15: 137507 Aborted                 (core dumped) qtodotxt

I can reproduce this on my side in a container by running e.g.

toolbox create testqtodotxt --release=f40
toolbox run --container testqtodotxt sudo dnf install -y $(cat ${PWD}/systemlibraries.txt)
toolbox run --container testqtodotxt sh ${PWD}/test.sh

where systemlibraries.txt reads:

libglvnd-glx
tk-devel
xcb-util-wm
xcb-util-image
xcb-util-keysyms
xcb-util-renderutil
libxkbcommon-x11

What could be the cause of / solution to this error?

P.S. Sidenote: Even though the stderr output says core dumped, I don't actually see a coredump anywhere, but maybe I don't know where to look.

P.P.S. Replacing system library tk-devel by python3-qt5-devel leads to the same error, while just removing it produces a different error:

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: linuxfb, minimal, offscreen, vnc, webgl, xcb.

/home/odmi/projects/dev/testpyqt5/test.sh: line 14: 133372 Aborted                 (core dumped) qtodotxt

P.P.P.S. qtodotxt documentation mentions the library python3-pyside as a requirement. Fedora provides python3-pyside6, which has qt6 dependencies as opposed to the qt5 dependency of qtodotxt. Installing python3-pyside6 doesn't help.

As explained by @musicamante: The mismatch in signatures between the qtodotxt and PyQt5 libraries is due to a change in more recent PyQt5 versions, and the pip version qtodotxt==1.9.0 not having been migrated. Thanks due to @musicamante for noticing that the git hub repo does have a fix committed.

Thus, to make qtodotxt work with the current PyQt5, don't pip install qtodotxt==1.9.0, but rather work with a repo clone:

git clone https://github.com/QTodoTxt/QTodoTxt/
