Application: kmail (4.14.6)
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.19.3-200.fc21.x86_64 x86_64
Distribution: "Fedora release 21 (Twenty One)"

-- Information about the crash:
- What I was doing when the application crashed:
Clicked on an email in an Imap inbox.  The email I clicked on was shows as the parent of another more recent email.  
- Unusual behavior I noticed:
I tried to restart kmail after the crash and it immediately crashed with a message to the effect that it could not access the collection.  I then ran "akonadict restart" after which I was able to restart kmail and access the email that caused the problem before.

The crash can be reproduced sometimes.

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