Application: konversation (1.7.4)

Qt Version: 5.9.4
Frameworks Version: 5.42.0
Operating System: Linux 4.15.9-200.fc26.x86_64 x86_64
Distribution: "Fedora release 26 (Twenty Six)"

-- Information about the crash:
Here is the context:
gedit is open and has a document open with modifications.
I click on shutdown withing gnome-shell
gedit offers me to cancel the shutdown in order to save the modifications.
Konversation turns to a half-closed state and crashes when I try to look at its window.

The crash can be reproduced every time.

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