It's not garbage but chunked transfer encoding, as indicated by
response headers. Consult RFC 2616 for details.
On the other hand, it's quite possible that the snipped above
isn't real conversation but data with chunked encoding already
removed. In raw data (try telnet) you should get duplicated
chunked markers in this case. This may indicate backend bug
returning chunked to nginx despite the fact that it uses HTTP/1.0
for backend connections.
Anyway, it doesn't looks like memcached problem.
