Application: konversation (1.7.2)

Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.13.0-16-generic x86_64
Distribution: Ubuntu 17.10

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

I just had Konversation running in the background, connected to multiple IRC servers. Even without interacting with it, it just randomly segfaults after awhile. 

Sometimes it's a few minutes, sometimes a few hours. 
I never had a problem with it crashing at all (It would be up for days), until I updated to Ubuntu 17.10, then this problem started.

The crash can be reproduced every time.

-- Backtrace:
Application: Konversation (konversation), signal: Segmentation fault
