KDE->System Settings->Application Appearance->GTK+ Appearance->Widget Stylewhich right now is set to Clearlooks. The problem is that text in the selection bar is hard to read because the bar is dark and the text is black. An image is attached (Evo.jpg); sorry for the blurring, which is an artifact of jpg compression. Using the standard theme (oxygen-gtk) the problem is that the selection bar is almost invisibly light. Every theme has its own problem; the issues seem to be the same under LXDE; but Evolution displays everything properly under Gnome, with the selection bars intense blue and the selected text white.
