           Summary: KMail crash when replying to a message that failed to
                    load
           Product: kontact
           Version: 4.4.11
          Platform: Debian unstable
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: giuseppe.bilotta at gmail.com


Application: kontact (4.4.11)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.4
Operating System: Linux 3.2.0-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:

Trying to reply to a message in KMail

- Unusual behavior I noticed:

When selecting the message by clicking on the message header in the message
list pane, the message body pane was totally blank (not even the message
headers were shown).

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
