That suggests one of the packages in the ‘heads-guix’ channel has an
invalid URL (one for which ‘string->uri’ returns #f).

If you set COLUMNS=200 you should see the name of the package in the
backtrace.  :-)

That is correct.  I had a URL with content "FIXME" with url-fetch.

Still, I don't think this should happen.  Better to just print a normal warning
or error message.

Yes, but… it’s complicated: the assumption that the ‘uri’ field is a URI
or list thereof is made throughout the code.

Thanks,
