On a fresh KDE installation, the preferences for Kicker hide buttons are backwards.
The "Bottom/Right hide button" is enabled, and the "Top/Left hide button" is not. But the preferences page shows the exact opposite, and upon applying a change to a seemingly-unrelated thing (like turning off tooltips) the hide button settings are instantly reversed.
fixed in CVS HEAD and 3.1 branch
