            Bug ID: 387170
           Summary: Konversation randomly crashes after awhile
           Product: konversation
           Version: 1.7.2
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konversation-devel at kde.org
          Reporter: wodencafe at gmail.com
  Target Milestone: ---

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
