Notebook tabs upside down

[Jeffrey Barish]

Run XRCed.  The notebook tabs appear at the bottom of the notebook where
they belong, but they are drawn upside down (as they would be if they were
positioned at the top).  My own applications created using wxPython
demonstrate the same problem.  I am on Kubuntu 6.10, Python 2.4.3, wxPython
2.7.2, and XRCed 0.1.7-5.  I am told that the problem is due to a bug in
the GTK theme, which is what draws the tabs.  I am using the default
Kubuntu theme.  I thought of using System Settings to change from "Use my
KDE style in GTK applications" to "Use another style", but the change does
nothing and does not stick.  What do I need to do to get tabs drawn
correctly?
