Bug ID: 381371
Summary: KWrite crashed when closing a large HTML file
Product: kate
Version: 17.04.2
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: kwrite
Assignee: kwrite-bugs-n...@kde.org
Reporter: dennis.schri...@uni-heidelberg.de
Target Milestone: ---
Application: kwrite (17.04.2)
Qt Version: 5.7.1
Frameworks Version: 5.35.0
Operating System: Linux 4.8.0-53-generic x86_64
Distribution: KDE neon LTS User Edition 5.8
-- Information about the crash:
- What I was doing when the application crashed:
1. I opened a large HTML file (dump from facebook.com), which had much of its
contents on one line
2. I tried to edit it, but KWrite proved too slow, with long pauses when trying
to mark text using the mouse, and long reaction times to keystrokes
3. I clicked the close-window button (X)
4. KWrite took a while to react to it and then reacted by crashing
-- Backtrace:
Application: KWrite (kwrite), signal: Segmentation fault
