Version:           1.0 (using KDE 4.2.2)
Installed from:    Debian testing/unstable Packages

If I use a simple kdialog such as

$kdialog --yesno "Test"

And the I use the keyboard to select the option, then kdialog will always return the default option, not the real selected one. It does work if using the mouse.
This happens with every dialog systemwide, not only wes/no which is quite annoying if you are used to work without mouse.

$kdialog --yesno "Test"

user chooses yes with Tab+Enter --> 0
user chooses no with Tab+Enter --> 0
user chooses yes with mouse --> 0
user chooses no with mouse --> 1
