Comment from mailing list:


It's clear, it crash in OPenCV library used by Image Quality algorithm :

Application Specific Information: terminating with uncaught exception of type cv::Exception: OpenCV(4.5.1) /Users/gilles/Documents/7.x/project/bundles/macports/temp.build/ext_opencv/ext_opencv-prefix/src/ext_opencv/modules/core/src/matrix.cpp:811: error: (-215:Assertion failed) 0 <= roi.x && 0 <= roi.width && roi.x + roi.width <= m.cols && 0 <= roi.y && 0 <= roi.height && roi.y + roi.height <= m.rows in function 'Mat' abort() called

It's an exception. This one must be caught in digiKam code. Please report this problem in digiKam bugzilla, will be take a look later

A new pre-release digiKam-7.5.0 MacOS bundle is available with the change. Can you please test whether the problem can still be reproduced?

Maik, 

I processed my collection of photo from my MacBook Pro under last stable MacOS Big Sur, and there is no reproducible crash.
