Description Colin J Thomson 2014-05-17 11:37:59 UTC 
Application: kontact (4.13.1)
KDE Platform Version: 4.13.1
Qt Version: 4.8.6
Operating System: Linux 3.14.4-200.fc20.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

Composing an email and then went to attach a Jpeg and Kmail will crash. If I enable 
enable "detection of missing attachments" Kmail will not crash. Maybe related to
https://bugs.kde.org/show_bug.cgi?id=333778

- Custom settings of the application:

"detection of missing attachments"
Checkbox not selected - crash everytime when adding an attachment
Checkbox selected - No crash adding attachments, of various sizes and number.

The crash can be reproduced every time.

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