Ah, that's what's happening! Bugs are popping up in various emacs packages that don't use dh-elpa because users are doing partial upgrades to sid without installing the new emacsen-common. It's a bit heavy-handed, but having packages such as emacs-goodies-el (or w3m-el, see #903200) declare a hard dependency on emacsen-common >= 3.0.2 will prevent this issue from triggering. I confirmed this 3 Aug with clean chroot upgrades of buster from @/20180802T205558Z to sid.

Yes, to my eye that is what's causing this. On a related issue, it seems a number of users are upgrading emacs-goodies-el without installing recommends. At some point Emacs-goodies-el will become a dummy transitional package that only contains documentation. If these dependencies remain as recommends and users --no-install-recommends then they will lose functionality that was previously part of goodies—gives users maximum freedom to do so. Alternatively, we can make emacs-goodies-el hard depend on this packages. This is what a dummy transitional package usually does. A side effect of this is that some of the modes have heavier depends than in the past. Eg: eproject now depends on helm. Cheers, Nicholas
