Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
kmail crashes after entering the second imap password.

kmail had been working until system (kubuntu 9.04) had a hard lockup and forced reboot.  After reboot I cannot start kmail or kontact.
