https://bugs.kde.org/show_bug.cgi?id=507101 Malte Gerken changed: What|Removed |Added CC||[email protected] --- Comment #10 from Malte Gerken --- I also experienced the bug on Arch Linux and have rebuilt the package locally with the patch by Maik applied. The issue is resolved by that, face recognition works again and there is also no more error on startup. As that patch is most likely included in the latest AppImage I would assume that this also works, but have not tested it. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=507101 --- Comment #6 from Maik Qualmann --- Hi Gilles, I think we're still waiting for 4.12. I just noticed that Tumbleweed is also still on 4.11. It might be an API change in the cv::ml::TrainData class or a bug. I'll keep researching it. Maik -- You are receiving this mail because: You are watching all bug changes.
