mate-volume-control-applet crashes after wakeup from hibernate

[muesli4]

Whenever my computer is woken up from hibernate and I hover my mouse over the status icon of mate-volume-control-applet the program crashes. I never encountered the issue with --debug enabled (at least as far as I remember). This time I had it running from a terminal and caught the following output:

(mate-volume-control-applet:19648): Gtk-WARNING **: Calling gtk_widget_realize() on a widget that isn't inside a toplevel window is not going to work very well. Widgets must be inside a toplevel container before realizing them.

(mate-volume-control-applet:19648): GLib-GObject-CRITICAL **: g_object_ref: assertion 'G_IS_OBJECT (object)' failed

(mate-volume-control-applet:19648): Gdk-CRITICAL **: gdk_window_get_scale_factor: assertion 'GDK_IS_WINDOW (window)' failed
**
Gtk:ERROR:gtkwidget.c:5813:gtk_widget_get_frame_clock: assertion failed: (window != NULL)

Looks the same as https://bugs.debian.org/856072...
Which GTK+3 version do you have?

[muesli4]

Yes it does. My GTK+ version is 3.22.12.

[monsta]

Ok, can you try obtaining a backtrace via gdb?

[muesli4]

This is from a crash I had when my pulseaudio server was busy and I had no connection to it. My local pulseaudio daemon lost the connection. Then the applet crashed. (In short: I'm not entirely sure whether it's the same bug.)

I've never done this before, so let me know if I can do anything else. I added the complete output (of coredumpctl gdb): output.txt.

Update: I checked the coredump of this mornings crash and it seems to be the same bug.

[monsta]

Interesting, I didn't know about coredumpctl, will check it out later. I usually run the app via gdb manually and then get the backtrace with bt full command.

The backtrace shows that the bug is probably inside GTK+3 though... the library names hint about that.
Can you install the debug packages? It helps a lot, because the backtrace will contain all the function names, their argument values, the line numbers in the code, etc.
Which distro do you use? If it's Debian/Ubuntu or their derivatives, I can tell you the package names you need to install.

[muesli4]

I will probably have to rebuild GTK+3 from source as Archlinux does not include debug information by default (afaik it even strips existing information). It could probably take some time. :(

[monsta]

Yes, I heard about it several times. Other distros also strip the debug info, but they move it into separate packages which you can install if needed...

[muesli4]

I compiled gtk3 with debug symbols now (I would add it as a file, but github won't let me):

[monsta]

@raveit65: looks like https://bugzilla.redhat.com/1418334 is about this one, the backtrace is the same...

[raveit65]

Yes, nice bugs you will always find at rhbz :-)

[raveit65]

But as always, i was never affected by this issue. I use only suspend to ram sometimes.

[monsta]

Not that I actually searched rhbz... but google led me there when I looked for similar backtraces. 🙂
Seems like a rare bug, only 2-3 reports out there. It really looks like a bug in GTK+, but we'll probably have to find a workaround, and I have no idea about it.

[muesli4]

I think it is somehow related to pulseaudio and their native TCP protocoll, which allows to connect multiple instances over LAN. Several times the applet crashed when disconnecting and also after suspend to ram. This seems to be the trigger, but not necessarily the cause (which explains why it occurs seldom).

My guess is that the bug is connected to GtkStatusIcon, which is deprecated (making a fix unlikely).

[monsta]

It might be, but other tray icons of GTK+ apps, which probably also use GtkStatusIcon, aren't affected.

[raveit65]

Looks like this report is related too https://bugzilla.redhat.com/show_bug.cgi?id=1694251

[raveit65]

I opened a newer report with a proper and newer stacktrace.
#201
@muesli4
Can we close this one in favor for the other report?

[lukefromdc]

Is this one confirmed to be fixed by the last change to libmatemixer or not?
