DrKonqi auto-attaching complete backtrace.

1/22/23 - Something bigger is broken here.  I cannot perform updates and cannot add any wallpaper.  Desktop themes can still be installed. (I'll provide errors...)  -David

The Discover message on boot after update failure says:

Failed Offline Update
Failed to update 1 package
Error while installing package trying to 
overwrite '/usr/share/locale/ca/
LC_MESSAGES/libkscreen5_qt.qm', which is 
also in package libkf5screen7

When I attempt to update I show 101 items to update. The update shows me that it wants to remove many (30+?) files then seems to do a quick installation as it quickly progresses...

Failed wallpaper installation.  The following is shown after I attempt to download/install a wallpaper that I have not tried to download/install before.

Overwrite File

This file already exists on disk (possibly due to an earlier failed download attempt). Continuing means overwriting it. Do you wish to overwrite  the existing file?
'/home/ddustan/.local/share/wallpapers/02.jpg'

It appears to be that in downloading wallpaper I have two resolution options to download for many wallpapers. 01.jpg and .02.jpg. I downloaded two 02.jpg images and the second failed with the dialogue above. At this time I also experience the crash of Plasma. 
Perhaps I'm missing a 'Save as" dialogue but I'm not sure why I see all these simple file names on the wallpaper server?  In past KDE installs I have not seen this to my recollection.  -David

Update (Jan. 26)

After update installation this morning situation is better. Only issue that remains is that if a wallpaper is downloaded from "Get New Wallpapers" button/link in the "Desktop Folder Settings" window and saved, it does so at location /home/.local/share/wallpapers/ as expected. I have downloaded files from the "Download New Wallpapers" to the location and downloaded another with the same file name, a very easy task as some users use simply 01.jpg or 02.jpg for different resolutions... for all of their posted wallpapers. The only issue is this - I downloaded 01.jpg and then if I redownload the wallpaper or download a new wallpaper with the same file name, I am prompted to overwrite the file which I accept.  Plasma then crashes. For some reason, the original 01.jpg will not overwrite and Plasma crashes.  
~~Should I remove and reinstall the latest version of Neon? I think this problem may be with my installation ...

Davd

Decided to download and reinstall Neon. Previously stated issue still occurs as in note posted earlier today. Plasma still crashes when downloading and installing a previously used filename.

>KNS3::WidgetQuestionListener::askQuestion

This code is absolutely full of nested event loop and does nothing to track or maintain the lifespan of KNS::Question.

Git commit e9e0e3faa986757ba096dbe599468f395b3461d3 by Christoph Cullmann, on behalf of David Edmundson.
Committed on 30/01/2023 at 18:42.
Pushed by cullmann into branch 'master'.

Fix crash in QQuickQuestionListener

The code path is:
 - we create a Question object
 - we show a prompt
 - we start a nested event loop to get this into a syncronous API
 - we return the result to the question object

The lifespan of the question object is not controlled by the listener,
during the nested event loop anything could have happened including
deletion.
