Samba dumps core when accessing printer options

Issue

• Upgraded to samba3x 3.6 from samba 3x 3.5:

samba3x-winbind-3.6.6-0.136.el5
samba3x-client-3.6.6-0.136.el5
samba3x-3.6.6-0.136.el5
samba3x-swat-3.6.6-0.136.el5
samba3x-domainjoin-gui-3.6.6-0.136.el5
samba3x-common-3.6.6-0.136.el5

After that, when I access printer properties (under printer and faxes) samba core dumps:
