            Bug ID: 372065
           Summary: Konsole crashes on average once a day
           Product: konsole
           Version: 16.08.2
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: metellius at gmail.com
  Target Milestone: ---

Application: konsole (16.08.2)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.4.0-45-generic x86_64
Distribution: KDE neon User Edition 5.8

-- Information about the crash:
Happens regardless of whether the window is focused or not.
Has been happening after konsole got a set of new features some months back
(one concrete change I remember that might help determining the point in time
is that I noticed the slide-from-the-left animation in the theme selection
dialog in the preferences was gone)

Running KDE neon, all packages updated.
I have not been able to pinpoint any common denominator for the crashes, it
seems completely random.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
