Application: kwrite (4.3.65 (KDE 4.3.65 (KDE 4.4 >= 20090820)))
KDE Version: 4.3.65 (KDE 4.3.65 (KDE 4.4 >= 20090820))
Qt Version: 4.5.1
Operating System: Linux 2.6.30-ARCH i686
Distribution: "(none)"

What I was doing when the application crashed:
KWrite crashed after creating a new document (Alt + F2 kwrite), pasting some content from the clipboard and pressing Ctrl + S

I'm using Qt 4.5.2 and daily kde builds provided from an external repo (build from 24.8)
