Application that crashed: kcmshell4
Version of the application: 
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.31-ARCH x86_64

What I was doing when the application crashed:
I repeatedly clicked on "test" in the flite sound configuration window, as I did't hear anything. Then a segfault occured. (I clicked very fast I guess)

 -- Backtrace:
Application: KDE Control Module (kcmshell4), signal: Segmentation fault
