The same problem happened to me again, this time on git commit 710f3ce,
while running 'guix system build'.  I've attached another transcript.

The binary junk is immediately followed (with no intervening newline) by
the message:

http://hydra.gnu.org/2zadn0b2kljwlsyarr3j5rz44yi2pvs3.narinfo' failed: 502, 
"Bad Gateway"

This suggests that nginx had a problem fetching it from hydra-server on
port 3000.  Repeating the same command worked properly.
