Updated gnome-session packages that fix one bug are now available for Red Hat Enterprise Linux 5.
The gnome-session package provides a utility to start up and manage the GNOME desktop session. Gnome-session starts up other core components of GNOME and handles log-outs and saves the sessions.
Prior to this update, the gnome-session utility did not fully honor the "Hidden=" key in autostart desktop files. As a consequence, users could not mark autostart files as Hidden= in their home directory to disable autostart files in system directories.With this update, gnome-session allows users to "mask" system autostart files by installing a file of the same name in ~/.config/autostart with a key Hidden=true when loading autostart files.
All users of gnome-session are advised to upgrade to these updated packages, which fix this bug.
