Version:            (using KDE KDE 3.1.94)
Installed from:    SuSE RPMs
OS:          Linux

When scrolling through the message list view using the keyboard ("->") encrypted messages can cause KMail to crash.

To reproduce:
 - scroll to an encrypted message
 - continue scrolling to the next message
 - make sure the next message is being selected BEFORE the keyphrase dialog is being displayed (dialog is modal, but there is delay between hitting an encrypted message and displaying the dialog, probably when kmail parses the message. this delay can be substantial when the system load is high)
 - enter keyphrase and click ok or choose cancel in the keyphrase dialog

Also if you have entered the keyphrase before, KMail decrypts the message without crashing. This problem has already been existent in the KMail version that came with KDE 3.1
