Bug 401392

Application: yakuake (3.0.5)

Qt Version: 5.9.4
Frameworks Version: 5.45.0
Operating System: Linux 4.19.4-1.g2f38375-default x86_64
Distribution: "openSUSE Leap 15.0"

-- Information about the crash:
- What I was doing when the application crashed:
I had three tabs open. 
One had run the following sudo command: 
sudo systemctl status privoxy.service 
the other did check for network traffic
tcpdump -n -i lo port 8118

the third was opened empty. 

- Unusual behavior I noticed:
When closing the tcpdump related middle tab, the whole application crashed. 
this happened irregularly in the past too. For what I recall always with multiple tabs open.

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