1.59.1. RHBA-2010:0806: bug fix update
Updated kdebase packages that resolve an issue are now available for Red Hat Enterprise Linux 5.
The K Desktop Environment (KDE) is a graphical desktop environment for the X Window System. The kdebase packages include core applications for the K Desktop Environment.
* Previously, the 'kdesktop_lock' process did not run on multi-user systems when another user had already ran an instance of 'kdesktop_lock'. This update allows 'kdesktop_lock' to work on multi-user systems when multiple single users are logged in. ( BZ#499442
All users of kdebase are advised to upgrade to these updated packages, which resolve this issue.
