SUMMARY
When i launch any command on face detection (including "Clear and rebuild all training data"), digikam abort. This bug occurs with or without YOLO v3.

STEPS TO REPRODUCE
1. Launch digikam
2. Execute "Scan for faces" on an album or a collection

OBSERVED RESULT
/usr/include/c++/12.2.0/bits/stl_vector.h:1123: std::vector<_Tp, _Alloc>::reference std::vector<_Tp, _Alloc>::operator[](size_type) [with _Tp = float; _Alloc = std::allocator<float>; reference = float&; size_type = long unsigned int]: Assertion '__n < this->size()' failed.
Aborted (core dumped)

EXPECTED RESULT
Faces detection ends without core dump.

Comment 1 Maik Qualmann 2023-01-22 13:18:45 UTC 
Problem is already known here. The cause is the new openCV-4.7.0. It crashes deep in the openCV DNN module, I suspect a bug in openCV at the moment.

Comment 2 Maik Qualmann 2023-01-22 13:22:50 UTC 
This could be the cause, the question is whether it is actually part of openCV-4.7.0 - 2 days before the release?

I confirm that everything works if I build digikam with opencv 4.6.
