Could be a corrupted file, that causes the problem.
Can you attach the output of 'dpkg -L kde-guidance | grep '\.py' | xargs md5sum {}' as a text file.
What happens if you run /usr/share/apps/guidance/displayconfig.pyc ?









dpkg -L kde-guidance | grep '\.py' | xargs md5sum {}
md5sum: {}: No such file or directory
