You're probably using fglrx? (Disable blur and set the scale method to "smooth" in this case, "kcmshell4 kwincompositing", 3rd tab) *** This bug has been marked as a duplicate of bug 270818 ***
I confirm you that I'm using fglrx. I was using the "rapid" method now I set "smooth" Thank you thi is the output of kcmshell4 kwincompositing SSISNET\diego@pc-diego:~> kcmshell4 kwincompositing OpenGL vendor string: ATI Technologies Inc.

crash occured in the blur effect, which must be disabled. smooth & fast should both be fine, where smooth will likely look better - only lanczos will break on that driver replacement ;-)
