My script works fine on centos5 - its centos 6 its not working on.

This issue seems to be related to dbus. gconftool-2 now uses dbus and
when running commands
like from cron to talk to the running X session its not happening correctly.

I found some posts thats talks about setting DBUS_SESSION_BUS_ADDRESS
and that seems to work "sometimes" but not always.

Was wondering if anyone has run into this also and if there is a good fix?
