<p><code>geany 1.37 (git >= ea649d80) (built on 2020-05-21 with GTK 3.22.30, GLib 2.56.4)</code></p>
<p>On exit from Geany, the document list component of the addons plugin causes an error message:<br>
<code>Gtk-CRITICAL gtk_widget_destroy: assertion 'GTK_IS_WIDGET (widget)' failed</code></p>
<p>I have narrowed it down to the <code>ao_doc_list_finalize</code> function, and found that the <code>priv->overflow_menu_item</code>, though non-null, is invalid, i.e. <code>GTK_IS_WIDGET</code> returns false, exactly as the error message claims.</p>
<p>Not sufficiently familiar with the code to guess where the corruption is occurring, and hoping the maintainer may be able to shed some light.</p>
<p>Not a major problem, as the app is exiting anyway, just annoying.</p>
