The problem is in missing meld gschema. For some reason setup.py of meld doesn't install it. I've added a patched version to my overlay https://github.com/rion-overlay/rion-overlay/tree/master/dev-util/meld more details: https://gitlab.gnome.org/GNOME/meld/-/issues/455 Reproducible: Always
I had this exact problem. I applied the solution outlined in these two posts, and it worked for me: https://forums.gentoo.org/viewtopic-t-1111592-highlight-elogind.html https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=180fa85d7d00aea463c399f70348beaad9166eb7 Basically edited a system file, re-emerged dev-util/meld, and then reverted the system file back to its original state. I'm not sure if this info helps, I don't know what the problem is or why this solution works. Just typing stuff in as root like an Ubuntu user.
This is a regression from https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=180fa85d7d00 Many other files disappear after a re-emerge too.
