            Bug ID: 402267
           Summary: Konsole crash with minimal system load
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: mzipay at gmail.com
  Target Milestone: ---

Application: kdeinit5 (18.08.3)

Qt Version: 5.11.1
Frameworks Version: 5.52.0
Operating System: Linux 4.19.8-200.fc28.x86_64 x86_64
Distribution: "Fedora release 28 (Twenty Eight)"

-- Information about the crash:
- What I was doing when the application crashed:
Editing C sources in Vim within Konsole. I had 4 files opened in separate Vim
instances; three of them backgrounded and one I was actively working on in the
foreground. Also had Chrome running with 6 open tabs, and Quod Libet playing my
music library. KDE, Vim and Quod Libet are all from current Fedora 28 repos,
and Chrome is from the stable channel.
I got up to get a coffee, and my screen locked while I was away. As soon as I
came back and unlocked, I brough Konsole to focus and it crashed.

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