Gtk Critical log message

[rgmf]

When you open segments app then it gets several Gtk-CRITICAL messages:

(pyopentracks:21096): Gtk-CRITICAL **: 17:18:18.420: gtk_bin_get_child: assertion 'GTK_IS_BIN (bin)' failed

(pyopentracks:21096): Gtk-CRITICAL **: 17:18:18.420: gtk_menu_item_get_submenu: assertion 'GTK_IS_MENU_ITEM (menu_item)' failed

(pyopentracks:21096): Gtk-CRITICAL **: 17:18:18.420: gtk_widget_set_sensitive: assertion 'GTK_IS_WIDGET (widget)' failed

Executing debugger with the option G_DEBUG=fatal-criticals can help to catch where the issue is because program will be stopped when these errors appear.
