What is the bug or the crash?

Today, from GitHub interface, I synced my master branch with the upstream one. Probably just after e186ae6.
It resulted in my branch

While from upstream branch the history is

Looks like my branch ran locally the sipify action, diverging then from the upstream master.

I don't know if we should limit the action scope to the qgis/QGIS repo or only run it in particular contexts (PR?) or disable it on my side, so I'm opening this issue report, so that most qualified people fix it/advise appropriately.

Steps to reproduce the issue
