Segmentation fault on PAP calling

I'm using FreeRADIUS 1.1.4 compiled from sources on Debian Etch.
I backend against LDAP with hashed password. Now I'm trying to configure
authentication to use with WPA, but it segfaults on calling PAP:

Segmentation fault

Some configuration snippets (maybe not useful, but the entire file would
have been too long I guess):

radiusd.conf:
...
modules {
	..
	pap {
		auto_header = yes
	}
	...
}
...
authorize {
	...
	ldap
	pap
}
authenticate {
	Auth-Type PAP {
		pap
	}
	...
}
...

If I revert the password to clear-text on LDAP, it runs fine and
authenticate.

Any ideas?
Thank you,
Giovanni Lovato
