Bug 399081

Application: konversation (1.7.5)

Qt Version: 5.11.1
Frameworks Version: 5.48.0
Operating System: Linux 4.18.9-200.fc28.x86_64 x86_64
Distribution: "Fedora release 28 (Twenty Eight)"

-- Information about the crash:
- What I was doing when the application crashed:
After the recent update, I noticed Kontact and Kmail not working properly.  As I toggle through various emails, it will produce errors.  I uninstalled KDE and then reinstalled KDE to see if problems resolved.  They did not resolve.  It still crashes, both Kontact and Kmail.  I have also noticed Kwin and Konversation crashing as well.

-- Backtrace:
Application: Konversation (konversation), signal: Bus error
Using host libthread_db library "/lib64/libthread_db.so.1".
