Application that crashed: kmail
Version of the application: 1.12.0
KDE Version: 4.2.95 (KDE 4.2.95 (KDE 4.3 RC1))
Qt Version: 4.5.2
Operating System: Linux 2.6.28-13-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I was configuring toolbar - adding new icons and moving there position when kmail crashed.
Last actions I perfomed before clicking Accept - moving down "Mark as read"

 -- Backtrace:
