Looking at guix/status.scm, maybe the following is important: >(('download-progress item uri > (= string->number size) > (= string->number transferred)) string->number returns #f if the input is malformed, so I guess that is what happens. I don't know _how_ that happens though. Detecting #f somewhere and emitting a warning or error like ‘warning: ‘the malformed string’, representing the number of transferred bytes, is malformed’ would be better. Fixing the underlying error would be ideal. I think I've seen this reported before, though I cannot find it again. Greetings, Maxime.
