I assume your timezone is definitely set? > (Obviously this is wrong even if it's not though.) I have an /etc/localtime, which gnome-control-center reads. You can see this function knows my current timezone because it prints it out. It then sets self->current_location to null but I don't understand why: https://gitlab.gnome.org/GNOME/gnome-control-center/-/blob/44.0/panels/datetime/cc-datetime-panel.c#L422
Oh, it's because self->timezone_dialog is null, and this getter method on the timezone dialog returns null for a null "self": https://gitlab.gnome.org/GNOME/gnome-control-center/-/blob/44.0/panels/datetime/cc-tz-dialog.c#L321

Is it because Gnome is expecting to build with -Wl,--export-dynamic? https://gitlab.gnome.org/GNOME/gtk/-/issues/2788 If I remove the patch and make an /etc/portage/env file that adds LDFLAGS="$LDFLAGS -Wl,--export-dynamic", gnome-control-center doesn't crash. However, this seems like a heavy-handed approach when there are macros specifically to ensure symbols end up exported.

That fixes it. Is there something I can read that explains why upstream > didn't notice this but Gentoo did? yay! At first, I was wondering if this is to do with glib-2.76 becoming stricter, but that's gfileinfo only: https://gitlab.gnome.org/GNOME/glib/-/commit/4cad66580b698e01d196cddc3b9950940a41fee9. So it's not that. Now I'm wondering if it's new Vala instead (>=0.56.4), or another change in glib-2.76?

Interesting... I have added some more to the MR. The old README.glade link in the GTK issue makes it clear they are needed before gtk_container_init_template. There was already a mix of putting them in panel_class_init and panel_init in gnome-control-center which I haven't resolved. We'll see.
So I guess this is bug 695326 reincarnated?
At least for me version 44.1 behaves normally
