I tried to reproduce over an hour, without luck. I was able to crash
gnome-panel once with a different strack trace, it crashed in
gtk_widget_hide(). Might be related to this, though. I'll file a
separate bug report about that one.
Back to this bug. The event was emitted from applet.c line 741:
static void
panel_applet_destroy (GtkWidget *widget,
AppletInfo *info)
{
GList *l;
g_return_if_fail (info != NULL);
info->widget = NULL;
registered_applets = g_slist_remove (registered_applets, info);
panel_applet_signaler_remove_applet(info); <==== line 741
queued_position_saves =
g_slist_remove (queued_position_saves, info);
if (info->type == PANEL_OBJECT_DRAWER) {
Drawer *drawer = info->data;
panel_applet_signaler_remove_applet() emits applet removed signal:
+ g_signal_emit(signaler, signals[APPLET_REMOVED], NULL, applet);
But as I said in comment #17, the crash seems to happen in "show" event
handler. I don't yet understand how this happens.
