Bug description

When I use the method EventControllerKey.set_static_name with a string literal param, then I add this controller to the window of the app, and then I open the GTK Inspector and visit the Controllers tab, I see one controller (I pressume it's the one I setted) with garbage characters (non-UTF-8), after navigating for a while, the application crashes with the Segmentation Fault (core dump) message.

I think it's because of the lifetime of the param not being 'static and the compiler optimizing it somehow.

fn set_static_name(name: Option<&str>) { ... }

Please provide a code sample as small as possible which reproduces the bug.

fn main() -> glib::ExitCode {
    let app: gtk::Application = glib::Object::builder().build();

    app.connect_activate(|app| {
        let window = gtk::ApplicationWindow::new(app);
        let key_controller = gtk::EventControllerKey::new();
        key_controller.set_static_name(Some("foo"));
        window.add_controller(key_controller);
        window.present()
    });

    app.run()
}

Backtrace

N/A because it doesn't panic, the process just get killed by the OS.

So the error is non-deterministic, I tried another run and the app didn't crash at any moment, but the garbage characters were still there
