Re: Debug for a GdkPixbuf CRITICAL error message...

[Glus Xof <gtglus gmail com>]

Hi again,

This code, taken from the official examples set & modified
conveniently, THROWS the same critical message...
---
#include <gtkmm.h>

int main(int argc, char *argv[])
{
  Gtk::Main kit(argc, argv);

  Glib::RefPtr<Gtk::StatusIcon> status_icon =
      Gtk::StatusIcon::create_from_file ("icon.svg");

/*
  Glib::RefPtr <Gdk::Pixbuf> pix_status_icon =
      Gdk::Pixbuf::create_from_file ("icon.svg", 48, 48);

  Glib::RefPtr<Gtk::StatusIcon> status_icon =
      Gtk::StatusIcon::create (pix_status_icon);
*/
  //Show a window:
  //The program will stop, and the status icon will disappear, when the window
  //is closed.
  Gtk::Window window;
  window.set_title("gtkmm StatusIcon example.");
  window.set_default_size(300, 300);
  Gtk::Main::run(window); //Shows the window and returns when it is closed.

  return 0;
}

What's wrong ?
