STEPS TO REPRODUCE
1. Run maintenance on
Build date: 9/26/22 3:32 AM (target: RelWithDebInfo)
Revision: 266ad6f694bec8083e7d9d09ba4c46ace6313052
Branch: qt5-maintenance

2. Check rebuild fingerprints
3. Kaboom after while amount of time, probably bad webp image
4. Here is it that little boi from "/home/pschonmann/Obrázky/optiky_kabely_wiki/SingleBandwidth_Chart2_1024x1024.webp" - https://share.schonmann.eu/m08pcw.webp

ADDITIONAL INFORMATION
Comment 1 Maik Qualmann 2022-10-01 15:11:49 UTC 
It crashes in ImageMagick. The WebP format should not be loaded with ImageMagick. Install the KImageFormatPlugins with WebP support. We'll have to further restrict ImageMagick, it's just too unstable.

Check in the digiKam settings under Plugins->Image Loader whether the QImage Loader is available and the WebP format is available. The QImage Loader internally has a higher priority for loading the WebP format.

Comment 2 Maik Qualmann 2022-10-01 15:31:08 UTC 
If I force the loading of WebP with ImageMagick here, I cannot reproduce a crash. ImageMagick is here at version 7.1.0-48 Q16-HDRI, which version are you using?

Comment 3 Petr Schonmann 2022-10-01 15:51:27 UTC 
Im using imagemagick from Mint 21 repository, thats

ii  imagemagick                                                 8:6.9.11.60+dfsg-1.3build2                    amd64        image manipulation programs -- binaries
ii  imagemagick-6-common                                        8:6.9.11.60+dfsg-1.3build2                    all          image manipulation programs -- infrastructure
ii  imagemagick-6.q16                                           8:6.9.11.60+dfsg-1.3build2                    amd64        image manipulation programs -- quantum depth Q16

But i tought appimage contains everything to lauch ( in this case imagick compatible with testing digikam 7.9 )

I can remove the image - its some kind of screenshot :)
Comment 4 Petr Schonmann 2022-10-01 16:18:07 UTC 
The settings in plugins ... both loaders have WEBP

Comment 5 Maik Qualmann 2022-10-01 16:22:39 UTC 
No, your QImage Loader has no WebP support...

Maik
Comment 6 Maik Qualmann 2022-10-01 16:24:04 UTC 
Ok, you're using an older version of ImageMagick, that's probably the cause.

Maik
Comment 7 Petr Schonmann 2022-10-01 16:34:05 UTC 
Ok, then im closing ticket as NOT A BUG and deleting problematic file.
