Another way to debug the package without compiling.

Hi there, I recently updated to Devuan Daedalus and I realized today, that the volume control applet was missing from panel in my MATE desktop environment. Now then, mate-media, which packages the applet, is not available in Debian Bookworm for some crashing reason[0]. Luckily, I found compatible packages from Ubuntu Jammy Jellyfish[1].

$ ls -1 Downloads/deb/ubuntu/
mate-media_1.26.0-1_amd64.deb
mate-media-common_1.26.0-1_all.deb
mate-media-dbgsym_1.26.0-1_amd64.ddeb

And with some shell-foo I repackaged the Ubuntu deb files, removing the zstd compression.

$ cat Downloads/deb/transform_zst_to_xz.sh
#!/bin/bash

[ -f "${1}" ] || exit 1

case "${1}"
in
    *.deb) ;;
    *.ddeb) ;;
    *) exit 2 ;;
esac

run()
{
    local filepath="$(realpath "${1}")"
    local filename="$(basename "${1}")"
    local pkgname="${filename%\.*}"
    mkdir "${pkgname}"
    pushd "${pkgname}" || exit 3
    ar x "${filepath}"
    mkdir DEBIAN
    tar -C DEBIAN --zstd -xf control.tar.zst
    tar --zstd -xf data.tar.zst
    rm -f control.tar.zst data.tar.zst debian-binary
    popd >/dev/null
    dpkg-deb --build "${pkgname}"
    [ ${?} -eq 0 ] && rm -rf "${pkgname}"
}

run "${1}"
exit 0

Also get libglib and libgtk3 debug symbols from debug apt source[2]. See here:

$ cat /etc/apt/sources.list.d/debug.list 
deb http://deb.debian.org/debian-debug/ bookworm-debug main
$ apt-get install libgtk-3-0-dbgsym libglib2.0-0-dbgsym

Finally, I can do

$ gdb /usr/bin/mate-volume-control-status-icon

and wait for the crash and get a more complete backtrace with infos from glib and gtk.

P.S.: There are several reports upstream and downstream, but all have missing symbols from glib and gtk. I had the very same backtrace, once, without information from glib and gtk data structures. Now, I am waiting for the next crash, which did not happen again.

Re: Another way to debug the package without compiling.

Finally got a backtrace. I had played a bit with the bluetooth speaker, had cycled it on and off several times. Switched off in the end. A while later hovered the icon in the notification area on the panel.

If you got any better understanding on what frame and variables to inspect, let me know. I have it open for a while longer...

Re: Another way to debug the package without compiling.

Now then, mate-media, which packages the applet, is not available in Debian Bookworm for some crashing reason[0]. Luckily, I found compatible packages from Ubuntu Jammy Jellyfish

Why didn't you try the version from unstable?

There are several reports upstream and downstream, but all have missing symbols from glib and gtk

This one seems to have those: https://github.com/mate-desktop/mate-me … -819028411

I think this would be better pursued in the bug report(s) rather than here. Sorry but I can't help otherwise.

EDIT: did you see the suggested workaround? The volumeicon-alsa package should also work in MATE if you can't get the native volume systray thingie working.

Re: Another way to debug the package without compiling.

Hi Head_on_a_Stick and thanks for your input! I did not know about the debug apt sources at that time. I guess there would have been a dbgsym package for mate-media, too. Well, now I can get Ubuntu packages installed on Debian based distros, hah.

The backtrace frames are empty like all the others, example snipped:

#22 0x00007ffff792c510 in  () at /usr/lib/libgtk-3.so.0
#23 0x00007ffff792c709 in  () at /usr/lib/libgtk-3.so.0

Mine have far more infos. I will check this evening, if I can get something out of the backtrace, heh. And yes, I reported my backtrace to the debian bug report.
