Bug 223416

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 2.6.28-15-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.

 -- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
