I’m confused because there’s a test for this: tests/test_gobject.py · 3.44.1 · GNOME / pygobject · GitLab that apparently passes fine python3.11 (#2693736) · Jobs · GNOME / pygobject · GitLab (you may need to scroll up to see the highlighted tests/test_gobject.py line)

Are others able to reproduce this? If so, any idea why GObject.Value(str, 'foo_bar') doesn’t work?
