Yes, the appropriate Ubuntu version and let me guess, you probably have an Intel Core 5. Maik
No this is a Xeon X5670 (6 core 2.93Ghz), from the Gulfton/Westmere EP architecture. Equivalent to the Core i7 970-990 series. I indeed read some bug reports concerning the Core i5 having something to do with the running kernel.

Hi, Can you check if this crash still exist with last weekly AppImage build available here : https://files.kde.org/digikam/ Thanks in advance
After testing for 2 days I haven't encountered the problem. I'll do some more this weekend. But so far it's all good.
Thanks for the feedback. I close this file now Gilles Caulier

It has been a while, but i've hit the same issue again. Release: digikam-7.2.0-rc-20210103T180117-x86-64-debug.appimage This time the issue does not appear during normal face detection / face recognition. But only appears when running it from the maintenance menu with "clear unconfirmed results and scan again" active. It is reproducible in this way on my system everytime I run it that way.

A new version of the AppImage that contains the latest patches is available. Can you please test whether the problem still exists? Maik

I'll keep testing it, but at the moment everything looks fine and I had no more crashes.
Thank you for testing and your feedback. I was pretty sure now that the problem was fixed. ((:-)) We subjected the image loader to a review and code optimization, which was definitely good. In the end, it was just a missing command that led to these weird crashes. This ends a long chapter of crashes the image loader. Maik
