Created attachment 146799 [details] Stack trace from MacOS crash reporter SUMMARY Digikam 7.6.0 seems to frequently crash when using the Albums UI while "Updating faces database" is in-progress. STEPS TO REPRODUCE 1. Launch Digikam 7.6.0 with a large photo library (mine has around 40,000 images) 2. Click on the "People" tab in the L side bar, then "Workflow", and begin "Detect Faces" or "Recognize Faces" 3. Click around in the UI repeatedly, selecting and unselecting images, etc., while the faces database update is in-progress in background OBSERVED RESULT Digikam crashes with EXC_BAD_INSTRUCTION (SIGILL) on Thread 0, CFRelease() called with NULL See attached stack traces for further information. (If helpful, I can re-run using a version with debug symbols.) EXPECTED RESULT No crash, normal operation SOFTWARE/OS VERSIONS macOS: 10.13.6 (High Sierra), 32GB RAM ADDITIONAL INFORMATION Not sure if this is a problem with the Albums-MainView component or with the Faces-Engine, but since the stack trace is on Thread 0 and mentions "Digikam::ContextMenuHelper::addOpenAndNavigateActions" it seems like maybe it's coming from the UI...?

Created attachment 146801 [details] One more stack trace For completeness, here is one more stack trace obtained when replicating the behavior.

For future reference, there is an easier way to reproduce this behavior in 7.6.0... right-clicking to bring up the context menu on any DNG (or raw file?) causes an immediate crash with a similar stack trace. It will happen in Thumbnail mode if a multiple selection contains one or more DNGs.
I think the problem will be fixed with the next MacOS bundle. It crashes in the new Open with... menu, so for a file for which there is no MacOS standard app, it should trigger the crash. Maik
New MacOS version is available, is the problem still reproducible? https://files.kde.org/digikam/ Maik
I cannot reproduce the problem here with my macbook pro and digiKam 8.1.0 pre-release. I close this file now. Gilles Caulier
