            Bug ID: 340845
           Summary: Konsole crashes when scrolling to the bottom in vim
           Product: konsole
           Version: 3.90.900
          Platform: Exherbo Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: heirecka at exherbo.org

Qt Version: 5.4.0

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

I can't reproduce this every time, but sometimes when I scroll to the bottom of
a file in vim konsole crashes. I suspect it's trying to send a notification and
somehow fails in the process.

-- Backtrace:
Application: Konsole (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
