I ran into this bug with spacefm after upgrading to Debian 13, and I found an easy way to reproduce. Before the upgrade the `spacefm-gtk3` did not crash this way.
Steps to reproduce: - Press `Ctrl` 7 times while spacefm window has focus This produces the following output in the terminal: ``` (spacefm:233252): Gtk-CRITICAL **: 09:10:52.819: gtk_widget_get_window: assertion 'GTK_IS_WIDGET (widget)' failed (spacefm:233252): GLib-GObject-CRITICAL **: 09:10:52.819: g_object_ref: assertion 'G_IS_OBJECT (object)' failed (spacefm:233252): Gtk-CRITICAL **: 09:10:53.177: gtk_widget_get_window: assertion 'GTK_IS_WIDGET (widget)' failed (spacefm:233252): GLib-GObject-CRITICAL **: 09:10:53.177: g_object_ref: assertion 'G_IS_OBJECT (object)' failed (spacefm:233252): Gtk-CRITICAL **: 09:10:53.540: gtk_widget_get_window: assertion 'GTK_IS_WIDGET (widget)' failed (spacefm:233252): GLib-GObject-CRITICAL **: 09:10:53.540: g_object_ref: assertion 'G_IS_OBJECT (object)' failed (spacefm:233252): Gtk-CRITICAL **: 09:10:53.914: gtk_widget_get_window: assertion 'GTK_IS_WIDGET (widget)' failed (spacefm:233252): GLib-GObject-CRITICAL **: 09:10:53.914: g_object_ref: assertion 'G_IS_OBJECT (object)' failed (spacefm:233252): Gtk-CRITICAL **: 09:10:54.255: gtk_widget_get_window: assertion 'GTK_IS_WIDGET (widget)' failed (spacefm:233252): GLib-GObject-CRITICAL **: 09:10:54.255: g_object_ref: assertion 'G_IS_OBJECT (object)' failed (spacefm:233252): Gtk-CRITICAL **: 09:10:54.630: gtk_widget_get_window: assertion 'GTK_IS_WIDGET (widget)' failed (spacefm:233252): GLib-GObject-CRITICAL **: 09:10:54.631: g_object_ref: assertion 'G_IS_OBJECT (object)' failed (spacefm:233252): Gtk-CRITICAL **: 09:10:55.001: gtk_widget_get_window: assertion 'GTK_IS_WIDGET (widget)' failed (spacefm:233252): GLib-GObject-CRITICAL **: 09:10:55.001: g_object_ref: assertion 'G_IS_OBJECT (object)' failed (spacefm:233252): Gdk-WARNING **: 09:10:55.011: losing last reference to undestroyed window (spacefm:233252): GLib-GObject-CRITICAL **: 09:10:55.011: g_object_unref: assertion '!object_already_finalized' failed Segmentation fault ```
