Bug 9102

works for me.
What desktop are you using (GNOME3, GNOME Classic, KDE, ...)?
Is the net_applet processus still there after?
If not, can you start net_applet from a terminal, then redo your procedure
then report back any error message here.

GDB trace with symbols

actually it's segfaulting (and I've already seen that trace in others BR)

I am using KDE
Prosses' gone after right click. When I started from terminal then redo prosses it said segfault.

Sorry if someone has reported this bug.

Multiple reports are fine, we got more info this way such as a way to reproduce.

Any idea on this Thierry? Can I assign this bug to you?

it segfaults in the CHLD signal handler.
Commenting it out fixes it.

strange thing is that it has two threads and it dies in the other thread.

Blino, does that ring something to you?

Once we (un)connect once, it has two threads.
it's hard to debug as under strace, the ifup commands do not happen

And the winner is 
Not running this fixes it:
        $notification_queue->add({
            title => $old_description || $current_description || N("Network connection"),
            pixbuf => network::net_applet::get_state_pixbuf(),
            message => get_state_message($old_interface || $current_interface),
        }) if $show;

reduced to this line in ugtk2:
    eval { $notification->show };

Before we have one thread, after two threads

@blino: Giving that Gtk2::Notify isn't maintained since 2007, what about throwing those out?
Might be the fc patch on perl-Gtk2-Notify or libnotify

Source RPM: drakx-net-1.18-1.mga3 => drakx-net-1.18-1.mga3, Gtk2::Queue, perl-Gtk2-Notify, libnotify

ccing dbug & glib maintainers who may know why a thread is created for a syncrhonous operation?
or may know how to prevent glib to spawn threads?

Or maybe should we explicitely create a perl thread prior to loading/initializing gtk+2, and do all the notifications from this thread, thus needing some dialog API between the two threads.
libnotify sucks :-(

or fork() rather than threads.
Or if as action is used, forking notify-send instead.

what's strange is that we do not got such errors on mgaapplet though we've got some strange segfaults.
and mgaapplet also has 2 threads once a bubble has been shown...

For now, it's workarounded (not fixed) in drakxtools-15.31:
we no more display those notification bubbles.

But the root issue remains

Doing initialisation before forking or in random threads is a really bad idea generally.

It would likely be far easier to simply implement things by sending direct dbus messages in perl... Not that I'm volunteering :D

well libnotify is supposed to do that job for the apps.
Synchronously.
Without glib creating a thread behind.

I think I'll try rebuild libnotify6, link perl-Gtk2-Notify with it, reenable notification bubbles in order to see if it fixes it.
Anyway we'll have to report this upstream.
They've broken 8 years working code...

No more release critical as it's "workarounded"

Priority: release_blocker => High

net_applet segfaults in Mageia 3. Users haves many problems with Internet connection via net_applet.
