aaa-base 9.2-5.4

I received today aaa-base 9.2-5.4 via YOU. It replaced the original aaa-base 9.2-5.2. After this, my printing environment is not printing. I did try to install aaa_base-9.2-5.2.i586.rpm using YaST but it reports a warning related to conflicts. Is there a way to backout this YOU update?
