EAP-PEAP, SSL, Segmentation Fault

Hi,
Does anyone know what may be happening here?
I'm trying to get PEAP logins working from a wireless access point, and on
every login attempt (whether correct or incorrect username or password in
all combinations) FreeRADIUS Seg Faults.
I'm using the default certificates that come with FreeRADIUS (1.1.3), and
have also tried generating and self signing SSL certificates via openssl.
I'm testing the server on out local network, but the server will be
publically accessable once up and ready.
(also, what should the commonName be set as for the certificate, or does
this not matter?)
`uname -a` output
FreeBSD finc.01online.co.nz 6.0-RELEASE FreeBSD 6.0-RELEASE #0: Thu Nov 3

i386
Here is the output from `radiusd -XA` till the end of the login (my guess is
the SSL side of things isn't working):
