After Installation I get a blank page for Kreport 4.2

I don’t know why but a lot of folder had “s” attribute!
s - This indicated the setuid/setgid permissions. This is not set displayed in the special permission part of the permissions display, but is represented as a s in the read portion of the owner or group permissions

I had to remove the attribute with
(chmod a-s …) and solved all (was done by my IT Admin guy :))
Thanks Val for ur help!!
