-- Information about the crash:
- What I was doing when the application crashed:
Using gscan2pdf and gimp to manipulate pdf files.  Had just tried to open a postscript file.  Compositing was on, as opposed to previous crashes with compositing off.

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
