Application that crashed: kmail
Version of the application: 1.11.90
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.5.0
Operating System: Linux 2.6.29.2-9-default-jta x86_64

What I was doing when the application crashed:
After checking for new mail, killed kmail manually.
Then I had duplicated messages in the incoming dimap folder. But new incoming mail only appeared once.
I used the remove duplicated messages, and tried to see some messages, wich marked them as empty (and unknown date). Forcing the machine one step forward I checked again mail, and crash.
