Bug ID: 405834
Summary: Kate crashes when I Alt+Tab back to it
Product: kate
Version: 18.12.2
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: markus.la...@gmail.com
Target Milestone: ---
Application: kate (18.12.2)
Qt Version: 5.11.3
Frameworks Version: 5.55.0
Operating System: Linux 4.20.16-200.fc29.x86_64 x86_64
Distribution (Platform): Fedora RPMs
-- Information about the crash:
- What I was doing when the application crashed:
I was setting up the CTags extension for the first time. I pressed F1 to read
the help page for the extension. When I Alt+Tabbed back to kate, kate crashed.
- Unusual behavior I noticed:
Shortly before the crash, when I typed symbol names into the CTags extension's
search box on the first tab, they were resolved very slowly or not at all.
- Custom settings of the application:
I had selected the Breeze Dark schema and enabled the Build, CTags, Open
Header, GDB, Snippets Tool View, Symbol Viewer and Terminal Tool View
extensions.
-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
