            Bug ID: 380264
           Summary: KMail crashes when replying to email
           Product: kontact
           Version: 5.4.3
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: john.perry at usm.edu
  Target Milestone: ---

Application: kontact (5.4.3)

Qt Version: 5.7.1
Frameworks Version: 5.34.0
Operating System: Linux 4.10.17-200.fc25.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

I simply try to reply to an email. The application crashes reliably whenever I
try to replay to that email.

- Unusual behavior I noticed:

The content of some emails is not displayed in the main kmail window. When I
clikc the "Reply" button from this window, kmail crashes. However, if I
double-click on the email, thereby opening it in a separate window, the text is
displayed and kmail does not crash when I press "Reply" in the new window. I
can compose a reply and the message is successfully sent. Upon returning to the
main window, message content is still not displayed, and and kmail/Kontact
crashes when I click the "Reply" button.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
