           Summary: KMail crashes when opening encrypted message
                    (KMReaderWin::decryptMessage)
           Product: kmail
           Version: 1.9.50
          Platform: unspecified
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org
        ReportedBy: Regnaron web de

Version:           1.9.50 (using 4.00.80 (KDE 4.0.80 >= 20080104), Gentoo)
Compiler:          i686-pc-linux-gnu-gcc
OS:                Linux (i686) release 2.6.23-gentoo-r3

Steps to reproduce:

1) Create a new message.
2) Encrypt that message. (OpenPGP)
3) Store the message in the queue for later sending (message is going to be encrypted now)
4) Double click on the message in your outbox
5) See KMail crash

There also is another problem with this bug: KMail does not just crash, the encrypted Mail is gone after the next reboot. So at least I also experience a data loss here.

I am running kdepimlibs r765208 and kdepim r765208.

Note: If I store the mail on my hard disk, I can easily open it directly with KMail. (-> "open with...")

The backtrace for this crash is:
Application: Kontact (kontact), signal SIGSEGV
[?1034hUsing host libthread_db library "/lib/libthread_db.so.1".
