Bind not caching AAAA records

Hello.
I have bind set up as a cache and forwarder only. I am having trouble
getting bind to cache AAAA records. I can see from the rndc stats file that
A records are being cached quite nicely, but all AAAA requests are flowing
through to the upstream servers.
Here's a snippet from my stats file:
++ Incoming Queries ++
17394 A
17387 AAAA
++ Outgoing Queries ++
[View: default]
202 A
17354 AAAA
Unless I'm reading the stats output, it looks like all of the AAAA requests
are cache misses.
My bind.conf.options file has the following contents:
options {
recursing-file "/etc/bind/bind.recurse";
forward only;
minimal-responses yes;
statistics-file "/etc/bind/stats";
forwarders {
172.16.0.23;
} ;
recursive-clients 10000;
allow-query { any ; } ;
allow-recursion { any ; } ;
listen-on { any ; };
listen-on-v6 { any ; };
recursion yes;
};
The contents of my /etc/defaults/bind9 file is as follows:
//
# run resolvconf?
RESOLVCONF=no
# startup options for the server
OPTIONS="-u bind"
//
My operating system is Ubuntu 12.04.
Is there someone that can point me in the right direction? I tried googling
"Bind9 AAAA record not caching" and things like "bind AAAA cache hit" but
can't seem to figure out what's happening.
