Hi,
I'm still quite puzzled by this, but I'm relatively confident that
commit 2986ba899f5ee374008c501e26fb653147ed7891 ("gnu: cups: Replace
with 2.4.6 [fixes CVE-2023-34241].") caused the following wxPython /
pygobject script to fail:--8<---------------cut here---------------start------------->8--- $ guix time-machine --commit=2986ba899f5ee374008c501e26fb653147ed7891 \ -- shell --rebuild-cache --pure python python-pygobject python-wxpython gtk+ \ -- ./hang-repro.py --8<---------------cut here---------------end--------------->8--- Where hang-repro.py contains:

I've very puzzled as to why grafting CUPS could create such a problem :-). Help wanted! -- Thanks, Maxim
