Description stakanov 2023-09-17 18:01:50 UTC 
Application: kaffeine (2.0.18)

Qt Version: 5.15.10
Frameworks Version: 5.110.0
Operating System: Linux 6.5.3-1-default x86_64
Windowing System: X11
Distribution: openSUSE Tumbleweed

-- Information about the crash:
What is to be said: the "no idioneous card found" part was escalating with kernel 6.5.2 with no function (card disactivated when a Monatage chip was used). Now this has been restored with Kernel 6.5.3 but, the issue of complaining of not finding a suitable device and the segfault is still here. 
It might be that the following entries of journalctl give some hint on what happens here:

dmesg does give no hint.

The crash can be reproduced sometimes.
