This message is to do with CDE and it's underlying messaging system i.e ToolTalk. If you are unfamilar with ToolTalk, conceptually it is similar to DBUS on Fedora/Redhat/CentOS. It was developed by Sun.

Generally caused by CDE not being able to write files in a user's home directory. Often caused when a user's directory is NFS mounted. Lots of information and good advise available if you search the Web.
