            Bug ID: 413965
           Summary: Crash on close of tab
           Product: konversation
           Version: 1.7.5
          Platform: Debian stable
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konversation-devel at kde.org
          Reporter: zeroping+kdebugs at gmail.com
  Target Milestone: ---

Application: konversation (1.7.5)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-6-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)

-- Information about the crash:
- What I was doing when the application crashed:
Closing a channel's tab. (right click on channel -> close tab)

The dialog was in the process of coming up to ask me to confirm when it
crashed. I never got the full dialog. It's repeatable at least twice.

-- Backtrace:
Application: Konversation (konversation), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
