rtkit is installed by default for Karmic and this patch has been known about for a few months.
I think either the patch should be incorporated (I am using Linux eve 2.6.31-11-generic #38-Ubuntu SMP Fri Oct 2 11:55:55 UTC 2009 i686 GNU/Linux from linux-image-2.6.31-11-generic) or rtkit should not be part of the default install of ubuntu-desktop.
(rtkit should probably depend also depend upon the minimal kernel version that allows it to work correctly too).
