Application: plasmashell (5.24.1) Qt Version: 5.15.2 Frameworks Version: 5.91.0 Operating System: Linux 5.13.0-30-generic x86_64 Windowing System: Wayland Distribution: Ubuntu 21.10 DrKonqi: 5.24.1 [KCrashBackend] -- Information about the crash: - What I was doing when the application crashed: Tried adding the Activity Bar widget to my panel. - Unusual behavior I noticed: The entire desktop crashed. Then reappeared (restarted itself?). Then I'm unable to add widgets, i.e. nothing happens when I right click > Add widget.

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: > #18 0x00007fb6ed938415 in ?? () from /usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/draganddrop/libdraganddropplugin.so > #19 0x00007fb6ed938fd4 in ?? () from /usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/draganddrop/libdraganddropplugin.so Could you please install debug symbols for Plasma, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports > Then I'm unable to add widgets, i.e. nothing happens when I right click > Add widget.

Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please mark the bug as REPORTED so that the KDE team knows that the bug is ready to be confirmed. Thank you for helping us make KDE software even better for everyone!
Sorry for the lack of response. I can't quite figure out how to get the debug package(s). Tried installing kdelibs5-dbgsym (sudo apt install kdelibs5-dbgsym), as mentioned on the wiki, but that came up with no package found. Tried apt-cache search: USER - > apt-cache search kdelibs5* libkf5kdelibs4support-data - Porting aid from KDELibs4. libkf5kdelibs4support-dev - development files for kde4support libkf5kdelibs4support5 - Porting aid from KDELibs4. libkf5kdelibs4support5-bin - Porting aid from KDELibs4. The wiki page isn't very helpful, since not even the example of kdepim-dbg comes up when I try to use apt-cache search, and I'm not quite sure which application that was the culprit. sudo apt install libdraganddropplugin-dbgsym doesn't yield anything. When the crash occured, I got a list of something, but it wasn't really clear what I was supposed to do with them. On a side note, the crash/bug handler could benefit from contain info on what packages you need to install (i.e. hand-holding for). Currently it's "Please install debug symbols, here's a list of files" but that only showed file paths to some file or other, not "these are the packages you need to install". Is there some sort of "plasma mega debug package" I can install to get every debug symbol I might need? :D
You're probably having a hard time finding kdelibs5 because no such thing exists; for Qt 5, the old kdelibs package was split into 70-something individual "frameworks" packages. The debug packages you'll need are for Plasma itself; try searching for `plasma-workspace` and `plasma-desktop`.
Can't find anything dgbsym for those either :| USER - > apt-cache search plasma-desktop* kde-plasma-desktop - KDE Plasma Desktop and minimal set of applications kubuntu-settings-desktop - Settings and artwork for the Kubuntu (Desktop) plasma-desktop - Tools and widgets for the desktop plasma-desktop-data - Tools and widgets for the desktop data files plasma-desktop-dev - Tools and widgets for the desktop USER - > apt-cache search plasma-workspace* plasma-workspace - Plasma Workspace for KF5 plasma-workspace-data - Plasma Workspace for KF5 - data files plasma-workspace-dev - Plasma Workspace for KF5 devel files plasma-workspace-wallpapers - Wallpapers for Plasma 5 plasma-workspace-wayland - Plasma Workspace for KF5 - Wayland integration USER - > apt-cache search plasma-workspace-* plasma-workspace - Plasma Workspace for KF5 plasma-workspace-data - Plasma Workspace for KF5 - data files plasma-workspace-dev - Plasma Workspace for KF5 devel files plasma-workspace-wallpapers - Wallpapers for Plasma 5 plasma-workspace-wayland - Plasma Workspace for KF5 - Wayland integration
Sorry, I don't know enough about Kubuntu to help any further. Perhaps you could ask in a Kubuntu-specific help forum.
