Other reports can be seen on the Aur comments..

Steps to Reproduce

1. Try to install Scene Switcher from the AUR
2. ???
3. Whatever the opposite of profit is
   ...

Anything else we should know?

Also tried a variety of cache purging methods, including downgrading opencv from 5.0.6 to 5.0.0 ( this did nothing )

I spun up my own thing to get around it so it's no rush, but wanted to draw attention to it regardless

[WarmUpTill]

Should be resolved by #1670.
I will merge it as soon as the CI jobs are done.

Seems like "Haar Cascade Classifiers" have been move from the OpenCV core to opencv_contrib for the 5.x branch.
