Yes, the behavior is perfectly reproducible. But it was tied to one package definition. I tried modifying a few other definitions, with expected outcomes. So I set out to explore what is special about this package. It's a definition I had started last week and came back to for finishing touches. In the meantime, I had done a "guix pull", and with that update I had retrieved an almost identical definition in the "guix" channel. Someone else had beaten me to submitting the package! Unfortunately, when there are several packages with identical name and version number in two channels, Guix silently chooses one of them. It would probably be more useful to emit a warning. So I ended up editing a package definition which would undergo basic checking by Guile, but then be ignored. Cheers, Konrad.
