Bug 219215

Application that crashed: kmail
Version of the application: 1.12.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
In Kmail>Setting>Kmail Configure >Appearance> Layout > Shor folder list + Show favourite folder view + Show folder quick search 
this makes it crash 1st time then it runs fine
