[CentOS] Strange su behavior after installing latest CentOS updates

I did a "yum update" on my CentOS 6 systems yesterday for the first time in about a month and now have some automated processes failing because the PATH is not set up correctly when using "su".  The problem is very easy to see by comparing the output of the following two commands:

    # su - <user> -c "env | grep PATH"
    # su <user> -c "env | grep PATH"

Before yesterday's update, and on any CentOS 6.2 systems without the latest (in the last month) updates and all CentOS 5.8 systems, PATH contained anything that was set in /etc/profile.d, but it appears that it does not run anything in that directory after yesterday's update.  As I mentioned before, this is breaking a lot of automated process that relied on the PATH being set correctly when doing a "su - <user> -c ...".  Is this a known issue?  Is anyone else affected by it?  In case it matters, I'll include the list of all the packages that were installed yesterday at the end of this message.
