Numeric values are saved in the current locale
Glade 3.22.1
When I adjust a Gtk::SpinButton or Gtk::Adjustment, climb_rate or step_increment, the values are saved in the current locale, for instance de_DE which results in wrong floating point numbers. For instance a value of 0.1 or 0.01 are saved as 0,1 and 0,01, note the comma in the values. The values should be saved in locale C.
