GPaste build fails on 'configure'. Most likely it's conneted to
gobject-introspection package bump that happend recently.
https://gitlab.gnome.org/GNOME/mutter/-/issues/2625

> The issue is caused by gobject-introspection looking at the default value of properties and transforming them into strings, ClutterPathConstraint:path having a NULL default value, and ClutterPath having a string transformation function that is not NULL-safe.
