Using serf 1.3.x@2241 the error is raised by this code:

            /* Hide EOF. */
            if (APR_STATUS_IS_EOF(status)) {
                status = ctx->stream_status;
                /* If our stream is finished too, return SUCCESS so
                 * we'll iterate one more time.
                 */
                if (APR_STATUS_IS_EOF(status)) {
                    /* No more data to read from the stream, and everything
                       inflated. If all data was received correctly, state
                       should have been advanced to STATE_READING_VERIFY or
                       STATE_FINISH. If not, then the data was incomplete
                       and we have an error. */
                    if (ctx->state != STATE_INFLATE)
                        return APR_SUCCESS;
                    else
                        return SERF_ERROR_DECOMPRESSION_FAILED;
                }
            }

Breakpoint 2, serf_deflate_read (bucket=0x7ffff3cce038, requested=8000, 
    data=0x7fffffffd478, len=0x7fffffffd470) at buckets/deflate_buckets.c:355
355	                        return SERF_ERROR_DECOMPRESSION_FAILED;
(gdb) p status
$1 = 70014
(gdb) p ctx->state
$2 = STATE_INFLATE

So I suppose this is really a serf bug, it should be telling the caller that
server closed the socket in the middle of the data.
