Comment 2 Maik Qualmann 2020-07-12 20:07:43 UTC

The crash in DImg::load() is known. It mainly occurs on Intel CPU Core I5/7 on Ubuntu. We have currently deactivated OpenCL in OpenCV because it produces a memory leak. Please test the current digiKam-7.0.0 version in the next few days from here:

Thanks in advance

Comment 4 paazmaya 2020-07-15 08:26:41 UTC

Thank you for the information.
I tested with "digikam-7.0.0-20200713T054246-x86-64.appimage" and could not get the crash reproduced.
