+Description: Fix FTBFS withPython 3.12
+ When running in command line mode, the Gedcom and ProGen importers
+ were being run before the `gi.require_version` method, causing
+ Gtk 4.0 to be incorrectly loaded. This caused some unit tests to
+ fail.
+ Caused Gramps to be removed from Debian Testing and Ubuntu Noble.
+ Debian Bug - https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1061743 
+ Also needed to backport 2 commits from the Gramps 5.2 branch:
+ https://github.com/gramps-project/gramps/commit/47f392ef70618cfece86e5210c19c2c1a768a4e0
