I suspect (though I'm not certain) that qdbus-5.15.3 should have slot 5. When trying to do a world update, I'm getting blocks related to qt slot conflicts.
This is unlikely to be your issue. qdbus should always be the latest version AFAIK and therefore doesn't need to be slotted: https://github.com/gentoo/qt/pull/225#issuecomment-734961892. You can even see various reverse dependencies of it have been adapted to depend on :*. That's not an issue and is intentional. If you need help, please share the full world output: emerge -p -uvDU @world --backtrack=100 and emerge --info.
My bad. Looking into it more closely, I found that `spectacle` and `qtwaylandscanner` were missing in accept_keywords, and the stable version of spectacle depended on qdbus:5 whereas the latest one depends on qdbus:*.

No worries. I think we should probably mention this in the news item as a few people hit that kind of thing already.
