Created attachment 183504 [details] Output of "Components Information" with FFmpeg config and Features omitted SUMMARY I've had digiKam crash on me a few times, somewhat unpredictably, while using the "People" tab. I have a feeling it's related to Faces - Recognition and not Faces - Detection, though I could be wrong. STEPS TO REPRODUCE 1. Open the People tab. 2. Start scanning for faces. 3. Start tagging faces and accepting suggestions. OBSERVED RESULT digiKam crashes. EXPECTED RESULT digiKam does not crash. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Ubuntu 25.04 KDE Frameworks Version: 6.12.0 Qt Version: 6.8.3 ADDITIONAL INFORMATION The GNOME "Logs" application reports the following: > /tmp/.mount_digiKaJmlN4n/AppRun: line 261: 30699 Segmentation fault (core dumped) digikam $@ and, just before that: > Error in processing command line: Don't understand command line argument "-cl-no-subgroup-ifp"! > -cl-no-subgroup-ifp > Status -11: CL_BUILD_PROGRAM_FAILURE > OpenCL program build log: dnn/dummy > [ WARN:0@65.499] global ocl4dnn_conv_spatial.cpp:1931 loadTunedConfig OpenCV(ocl4dnn): consider to specify kernel configuration cache directory through OPENCV_OCL4DNN_CONFIG_PATH parameter. I've had this crash happen to me several times so far, but I'm aware that it may be difficult to reproduce. I appeared to have plenty of available memory and disk space. Run on a NVIDIA GeForce RTX 2060. (Abbreviated) "Components Information" is attached.
The crash appears to OpenCV DNN module. With the current 8.8.0 digiKam, we switch from the 4.11 to the new OpenCV release 4.12. Try to see if it"s reproducible : https://files.kde.org/digikam/ Best regards Gilles Caulier

Open digikam. 2. Open the People tab. 3. Go into Unconfirmed. 4. Select about 100 faces (all for one person) and press accept.
Please disable OpenCL in the digiKam settings under Miscellaneous->System. Restart digiKam and test if the crash still occurs. Maik
Turned off "Use OpenCL acceleration for AI models", restarted digikam, and everything seemed to work fine. Turned it back on, restarted, and it crashed while running a manually-initiated "Recognize faces only" scan (on all processors, IIRC).
