Gtk: gtk_notebook_get_tab_label: assertion 'list != NULL' failed

It appears to be a bug on DrRacket's side (or deeper), when closing a tab. Filed an issue here:

Gtk issue on close-tab

opened 05:02PM - 08 Oct 23 UTC

To reproduce: 1. Open DrRacket from the command line to see the error port outp…uts in the console. 2. Open a new tab. 3. Close the tab (either from the menu or with a keyboard shortcut) The following error message is displayed in the console: ``` Gtk: gtk_notebook_get_tab_label: assertion 'list != NULL' failed ``` While the tab does close and the message seems innocuous, it get displayed on the error port which breaks some tests (such as quickscript-test).
