I can confirm the reported behaviour for ibus on a fresh CD install of Kubuntu Lucid Lynx 10.04 on an AMD 64 system.
One consequent problem is that if I launch the KDE kate text editor version 3.4.5 for KDE 4.4.5 from the launchpad pparepos, I still get a "No Input Window" message from the ibus system tray icon. So, input method switching is not available in kate launched from an icon.
However, if I lauch kate from a KDE konsole terminal by typing
kate &
then I am able to access in kate the different languages I need through ibus.
FWIW, I think this is because my personal ~/.bashrc has the lines

FWIW, I think this is because my personal ~/.bashrc has the lines
export GTK_IM_MODULE=ibus
export XMODIFIERS=@im=ibus
export QT_IM_MODULE=ibus
but the non-availability of the system-wide alternatives as noted above make the ibus language options unavailable to kate launched from an icon.
