Bug ID: 460482
Summary: Repeated crashes when working in Faces view while face
recognition is running in the background
Classification: Applications
Product: digikam
Version: 7.9.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Faces-Workflow
Assignee: digikam-bugs-n...@kde.org
Reporter: jens-bugs.kde....@spamfreemail.de
Target Milestone: ---
SUMMARY -> $SUBJECT
I have a faces database where - for some reason - a lot of face rectangles are
bad. Some are shifted, some did not survive rotating the image and some are
even outside the image (because of cropping).
My workflow to correct this is:
STEPS TO REPRODUCE
1. In faces view, select one person
2. Inside this view, repeatedly select some images, right-click "Detect faces"
(to find the correct location of faces on this photo) and then immediately with
the same selection click on the red (X) icon to delete *this* face region
(because it's bad).
3. While face detection is running, repeat this to queue more detection.
OBSERVED RESULT
Eventually, after 5-10 minutes, Digikam will crash. This is the console output:

Beendet
Unfortunately, running this with debug symbols enabled doesn't crash, even
after 30 minutes of usage - possibly because of Bug 460464 in the current
-debug appimage. So I cannot present a backtrace.
EXPECTED RESULT
No crash. Consecutively adding (queuing) images to a running face detection
process should be handled by Digikam just as if all images are added at once.
SOFTWARE/OS VERSIONS: KDE Neon 20.04 with Digikam 64bit appimage 2022-10-12
(with and without debug).
