            Bug ID: 371346
           Summary: Konsole crashes randomly, even when not actively in
                    use
           Product: konsole
           Version: 15.08.0
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: shipbrook at gmail.com

Application: konsole (15.08.0)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-42-lowlatency x86_64
Distribution: Ubuntu 15.10

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

Working in another application (this time, Google Chrome). Konsole crashes
sporadically; sometimes it can be days between segfaults, other times it'll
crash within minutes of opening it. It doesn't matter whether it's the
foreground window or not, or whether any of the tabs are actually doing
anything or just sitting at the bash prompt.

The crash can be reproduced sometimes.

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