No statistics being returned with 3.1.x status site

[Graham Clinch]

Hi Folks,

Is anybody succeessfully getting statistics from a 'status' type port 
using v3.1.x?  It works as expected with 3.0.x, but with 3.1 I only get 
a plain 'Access-Accept'

-=-
$ echo "Message-Authenticator = 0x00, FreeRADIUS-Statistics-Type = 3" | 
radclient -x localhost:18121 status adminsecret
Sent Status-Server Id 101 from 0.0.0.0:44494 to 127.0.0.1:18121 length 50
	Message-Authenticator = 0x00
	FreeRADIUS-Statistics-Type = Auth-Acct
Received Access-Accept Id 101 from 127.0.0.1:18121 to 0.0.0.0:0 via lo 
length 20

The only change to the stock config is linking sites-available/status 
into sites-enabled:

[...]
server status { # from file /usr/local/etc/raddb/sites-enabled/status
} # server status
