Application: kmail (4.14.9)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 3.16.7-24-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Checking my mail inbox. The crash occurred when I selected the second message in a thread. Both messages were new, I had just read the first one and the second one was marked as unread. 

- Unusual behavior I noticed:
None, apart from the usual duplicate mails of KMail. Wasn't a duplicate in this case, though.


- Custom settings of the application:

The application retrieves mail from a couple of POP3 accounts, and I have several rules in place to automatically place messages in the corresponding folders. The rules did not apply to the messages that caused the crash.

The crash does not seem to be reproducible.

-- Backtrace:
Application: KMail (kmail), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
