Application: kontact (4.12.3)
KDE Platform Version: 4.12.3
Qt Version: 4.8.5
Operating System: Linux 3.13.6-200.fc20.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I had started kontact. After a while, I saw a cinnomon notification that I had 60 new emails. For some reason, it forgot the last email I was looking at yesterday and it resorted all of my email and left me at one from 2004. I scrolled to the bottom and only saw new 15-20 emails. I also saw that none of the filters had moved mail to folders (like trash for example). So, I had a feeling kontact had deadlocked displaying something and decided to close it. As soon as I did, it crashed.

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