kdesktop signal 11

greets! this should be, I hope, a simple repair. I was trying to upgrade TDE based on squeeze, had some problems and have ended up with a corrupt desktop. I can log into KDE, the desktop gets populated with background and kicker, wicd, etc but there is a great big error panel in the center which says " kdesktop crashed" and tosses signal 11. (it used to toss signal 6 but seems over that now.) I cannot start any terminal apps within kde though I can alt + Fn. I can start other apps but borders of the windows are not fully drawn. obviously KDE is unstable. looking for suggestions. google yields nothing. F. -- Felmon Davis Only a fool has no doubts.
