GNOME problem after upgrade 9.2 -> 9.3

Solitaire (invoked from a KDE screen) will not start (nor will anything that uses GNOME). I get the message (all on one line): sol: symbol lookup error: /opt/gnome/lib/libglade-2.0.so.o: undefined symbol: gtk_about_dialog_get_type I've tried re-installing various (libglade, gtk) packages from the DVD. Made no difference. Suggestions ? mikus
