Application: konsole (15.04.0)

Qt Version: 5.4.1
Operating System: Linux 4.0.4-301.fc22.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Konsoles crashes if "Bell in non-visible session" is enabled and set to play a sound.

Steps to reproduce:
1. enable "Play a sound" for "Bell in non-visible session"
2. run "ping localhost -Aa"
3. Minimize the window and wait for it to crash

The crash can be reproduced every time.

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