I've stared at your logs, the code and tried to reproduce this myself but I
haven't yet figured out why you get this.

Right, which it seems to do for me every time I issue a similar command. I
just can't trigger this problem! :-/

Now I've used a more recent curl version than you're using, but I can't recall
us having changed anything in this area for a long time...

Clearly the 'upload_done' field isn't set to TRUE there yet, which it is
supposed to do here:

All info messages are just there for info and thus benign. If it would be
truly bad, curl would return an error there.
