So in our case due to b4ba441d7c8 most likely.

Applying that makes it all pass, so I trust that it's a good solution and I'm pushing that.

Here's some choice of more problematic dependencies with counts from nix-review-tools [report](https://malob.github.io/nix-review-tools-reports). Only those [regressing since master](https://hydra.nixos.org/eval/1775625?compare=1775597#tabs-now-fail), verified locally on x86_64-linux (but usually regressed cross-platform): - [x] [`python310Packages.loguru`](https://hydra.nixos.org/build/186649877) (166) -...

I forgot to notify maintainers. - `loguru`: @jbaum98, @rmcgibbo - `cattrs`: @fabaff - `mailcommon`: @ttuegel, @vandenoever, @nyanloutre

I don't think `libsForQt5.mailcommon` is a channel blocker, so maybe it's OK-ish to let it regress on master?

That failure was triggered by cmake update in PR #185287. (though that information doesn't seem very useful)

Uh, so I worked around the failure for now.

I haven't tried that due to qt6 not being involved in our case.

This broke tests in `.bitstring`: https://hydra.nixos.org/build/187598212 (the "treewide" commit, according to my bisect)

In PR #187531
