[Bug 448084] Re: gnome-panel crashed with SIGSEGV in gtk_widget_show()
I have investigated this a bit. Based on stack traces the crash happens
here:
void
gtk_widget_show (GtkWidget *widget)
{
g_return_if_fail (GTK_IS_WIDGET (widget)); < line 3005
I'm assuming that the signal for this is attached here in gnome-panel
/panel-toplevel.c (line 2740):
signals [i++] = g_signal_connect_swapped (
toplevel->priv->attach_widget, "show",
G_CALLBACK (gtk_widget_show), toplevel);
And before the "show" signal is emitted, panel_applet_destroy() is
called from gnome-panel/applet.c. I'm guessing there's a race condition
which makes it possible to destroy PanelToplevel object and after that
send a show signal to the destroyed object.
I haven't been able to reproduce the problem myself, all tips how to do
it would help.

[Bug 448084] Re: gnome-panel crashed with SIGSEGV in gtk_widget_show()
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.

I have tried still to reproduce this, but no luck. The timing, or the combination of events, to trigger this seems to very tricky. -- gnome-panel crashed with SIGSEGV in gtk_widget_show() https://bugs.launchpad.net/bugs/448084 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-panel in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 704387] [NEW] Network state from connman not followed
Public bug reported: Binary package hint: empathy Empathy has support for connman, but it can be only enabled during compilation time with --with-connectivity=connman. Also nm and connman cannot be enabled at the same time and because of this connman support in ubuntu is disabled. Connman has a compatibility mode for network- manager, which can be enabled with '-c' switch, but empathy uses libnm- glib which does a lot more than just queries the network status and hence it doesn't work with connman at all. A better solution is to have a runtime check for connman and nm, compared to the awkward compile time check used currently. Actually the easiest might be to remove libnm and connman support altogether from empathy and instead use network-manager's GetStatus() method and StatusChanged signal. That way empathy would work with both network- manager and connman and no recompilation is needed. For example pidgin works just like this. empathy 2.32.1-0ubuntu1 on maverick ** Affects: empathy (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to empathy in ubuntu. https://bugs.launchpad.net/bugs/704387 Title: Network state from connman not followed -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
