Description Matthew Zipay 2018-12-18 00:08:59 UTC
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".

Same backtrace as in bug#398320, should be fixed in 18.12.0.
