           Summary: kmail crashes when scrolling a messagelist, which has
                    encrypted messages
           Product: kmail
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: message list
        AssignedTo: kdepim-bugs kde org
        ReportedBy: additionall.one gmail com


Version:           unknown (using KDE 3.5.5, Debian Package 4:3.5.5a.dfsg.1-8 (4.0))
Compiler:          Target: x86_64-linux-gnu
OS:                Linux (x86_64) release 2.6.18-4-amd64

When scrolling through the messages in a folder by continuously holding down the "previous/next message" button (in my case, the shortcuts are Left/Right) Kmail crashes if the folder has at least one encrypted message. 

The way it happens is a dialog asking for the passphrase pops up, and when you hit Esc the dialog closes and Kmail crashes. The crash is easily reproducible. 

I am almost certain that the problem consists in the fact that by the time the dialog asking for the passphrase opens, the message which is selected is not the message which is encrypted (for me, it was 2 or 3 messages further). The crash occurs even if you enter the correct passphrase in the dialog.
