Bug ID: 410129
Summary: System completly hang after opening a 144MB file with
kwrite
Product: kwin
Version: 5.16.3
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: isalgue...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.16.3)
Qt Version: 5.12.3
Frameworks Version: 5.60.0
Operating System: Linux 4.18.0-25-generic x86_64
Distribution: KDE neon User Edition 5.16
-- Information about the crash:
- What I was doing when the application crashed:
I downloaded SoapUI installer from here
https://www.soapui.org/downloads/soapui.html. It downloads a shell script, so I
opened with kwrite to take a look (I tend to not execute random things from
the internet without checking them first ¯\_(ツ)_/¯) without realising that ths
script was so huge. Moved myself around that shell script with Av Pag and
everything stoped responding, I couldn't even log in in a text mode terminal.
After a restart, this kwin segfault report was here.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
