Application: plasmashell (5.24.4) Qt Version: 5.15.3 Frameworks Version: 5.92.0 Operating System: Linux 5.15.0-41-generic x86_64 Windowing System: X11 Distribution: Ubuntu 22.04 LTS DrKonqi: 5.24.4 [KCrashBackend] -- Information about the crash: - What I was doing when the application crashed: from the desktop panel (the system tray) I opened the widget "win7 volume mixer" clicking the icon, then I clicked the speakers icon (in my case HDMI) to check which audio profile is being used, if I do this again, next time it will crash, this happens everytime - Custom settings of the application: no real custom settings, only worth noting is that both the default audio volume icon/item and the win7 volume mixer are enabled at the same time (I have both icons active in my system tray, which is how I want it) and I'm also using version 26 (v26) The crash can be reproduced every time. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault [KCrash Handler] #4 0x00007f924442051b in ??

Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong: > #6 0x00007f9229dd0d98 in ?? () from /usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/plasma/components/libplasmacomponentsplugin.so Could you please install debug symbols for plasma-workspace, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports Thanks again!

See > https://community.kde.org/Guidelines_and_HOWTOs/Debugging/ > How_to_create_useful_crash_reports > > Thanks again! sorry I'm a novice at this I tried first running the commands sudo apt install plasma-workspace-dbg and sudo apt install plasma-workspace-dbgsym but both fail to install, I also tried installing this sudo apt install kubuntu-debug-installer but it seems to not make a difference, I tried reproducing the crash and then on the kde crash handler I clicked the button install debug symbols, but it didn't work too (i'll add the screenshot), also o the page "how to create useful reports" you added, this link was down https://wiki.kubuntu.org/DebuggingProgramCrash, idk if I need it. Finally somebody seems to be also dealing with this: https://askubuntu.com/questions/1143321/where-are-the-debug-symbols-for-plasmashell-kubuntu-19-04 and one of the answers recommend executing this command and some others sudo apt install plasma-workspace-dev like suggesting that this should work instead of -dbg or -dbgsym packages (I really don't understand much but it seems related to my problem of not findings debug symbols packages) That's my experience so far, I hope it's useful or at least that you can guide me on what should I do next.

I don't use Kubuntu so I'm not familiar with the process needed to make this work there, sorry. I would recommend seeking assistance on a Kubuntu-specific forum or chatroom.
I did find https://wiki.ubuntu.com/Debug%20Symbol%20Packages, so maybe that can help.
Reading on the forums it seems I'm supposed to first report issues on forum.kde.org before doing it on bugs.kde.org: https://forum.kde.org/viewtopic.php?f=289&t=122020 (I didn't know this) So I will do that, I'll report back if I receive a solution or any other info.
You can post bug reports here first, it's fine. Especially for crashes.
(In reply to Nate Graham from comment #6) > I did find https://wiki.ubuntu.com/Debug%20Symbol%20Packages, so maybe that > can help. I was able to install debug symbols using your link, it failed to fetch packages first with the message on the terminal: W: GPG error: http://ddebs.ubuntu.com jammy-updates Release: The following signatures were invalid: BADSIG C8CAB6595FDFF622 Ubuntu Debug Symbol Archive Automatic Signing Key (2016) <ubuntu-archive@lists.ubuntu.com> but then I tried again installing the optional sources at step 1 and apt update seems to work now: Ign:6 http://ddebs.ubuntu.com jammy InRelease Ign:7 http://ddebs.ubuntu.com jammy-updates InRelease Ign:8 http://ddebs.ubuntu.com jammy-proposed InRelease Get:9 http://ddebs.ubuntu.com jammy Release [40.4 kB] Hit:11 http://ddebs.ubuntu.com jammy-updates Release Get:13 http://ddebs.ubuntu.com jammy-proposed Release [40.5 kB] It lets me install -dbgsym for plasma-workspace on the terminal: Get:1 http://ddebs.ubuntu.com jammy/universe amd64 plasma-workspace-dbgsym amd64 4:5.24.4-0ubuntu1 [95.5 MB] now on kde crash handler I'm able to install debug symbols with the button "install debug symbols" except for 2 components (I'll attach the image) but still, the kde crash handler says the crash information is not useful (probably because of the debug packages missing)

It's frustrating to me as a bug triager that Ubuntu users have such a bad experience installing debug symbols.
(In reply to Nate Graham from comment #11) > It's frustrating to me as a bug triager that Ubuntu users have such a bad > experience installing debug symbols. Indeed, I thought this bug reporting would go smooth.
somebody replied to me on kubuntu forums: https://www.kubuntuforums.net/forum/currently-supported-releases/kubuntu-21-10-impish-indri/desktop-environment-support-aa/664418-plasma-5-24-4-crashes-when-switching-audio-from-kde-widget#post664421 I also reported the issue on the github issues page of the widget: https://github.com/Zren/plasma-applet-volumewin7mixer/issues/25
