--- Comment #4 from Olivier Fourdan <fourdan at xfce.org> ---
Please check the code, this is simple case of a “use-after-free” with a
possible “double free”.

When clicking the “tic-tac-toe” window, the dialog is destroyed in
`panel_dialogs_show_about_email_hook()` and reused again in
`panel_dialogs_show_about()` (`if (GTK_IS_WIDGET (about_dialog))
gtk_widget_destroy (about_dialog);`)
