……GtkWidget *file_chooser_dialog;……gtk_widget_destroy (file_chooser_dialog);/*error message at this line*/ On Windows Vista(SP1),I run the program step by step,and see an errormessage "GLib-GObject-CRITICAL **: g_object_unref: assertion 'G_IS_OBJECT(object)' failed" occurs.However,the same code runs with no error under Ubuntu 8.04!So I'm wondering if it's a bug of gtk_widget_destroy?-- View this message in context: http://www.nabble.com/Is-this-a-bug--tp21145590p21145590.htmlSent from the Gtk+ - General mailing list archive at Nabble.com. _______________________________________________gtk-list mailing listgtk-list@xxxxxxxxxxxxx://mail.gnome.org/mailman/listinfo/gtk-list
