xscreensaver-auth exit with Signal 6

[whywhy]

My xscreensaver is not displaying the password prompt when it lock the screen.

the following from the xscreensaver log seem indicate that xscreensaver-auth is dying :

xscreensaver: 11:15:10: pid 10966: launched xscreensaver-auth --verbose
xscreensaver-auth: 11:15:10: initial effective uid/gid was root/users (0/100)
xscreensaver-auth: 11:15:10: changed uid/gid to booboo/users (1000/100)
xscreensaver-auth: 11:15:10: running as user "booboo"

xscreensaver-auth: 11:15:10: pam_set_item (p, PAM_TTY, ":0") ==> 0 (Success)

xscreensaver-auth: 11:15:10: theme: default
xscreensaver: 11:15:10: pid 10966: xscreensaver-auth exited with signal 6

I have already re-emerge pam and xscreensaver.
any suggestion ?

Signal 6 is SIGABRT. Can you obtain and examine a core file from the crash?
