    78.30%  ./.libs/libwebkitgtk-1.0.so.0.0.1                                GtkLauncher
                |--86.18%-- WebCore::boxBlur(WebCore::CanvasPixelArray*&, WebCore::CanvasPixelArray*&, unsigned int

And yet again this is to blame on boxBlur, the same problem that makes
identi.ca scroll slooooowly. There is a patch in the works, and I plan
to integrate it into the package after the ICU migration, if it works
