Application: kontact (4.11.3)
KDE Platform Version: 4.11.3
Qt Version: 4.8.5
Operating System: Linux 3.11.9-200.fc19.x86_64 x86_64
Distribution: "Fedora release 19 (Schrödinger’s Cat)"

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

This is a bit weird bug, but what happened is this: I had my Kontact minimized, I opened it, then after a couple of seconds I double clicked (by error, it wasn't intentional) on the message area and Kontact window instantly disappeared!

I don't have any way to reproduce the bug at will.

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