Bug ID: 465460
Summary: Crash when deleting lines
Classification: Applications
Product: kdiff3
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: application
Assignee: reeves...@gmail.com
Reporter: benidan...@yahoo.de
Target Milestone: ---
Since the crash reported didn't let me report the bug, I copied the kcrash file
here:
Application: kdiff3 (1.9.70 (64 bit))
Qt Version: 5.15.8
Frameworks Version: 5.102.0
Operating System: Linux 5.15.0-58-generic x86_64
Windowing System: Wayland
Distribution: KDE neon 5.26
DrKonqi: 5.26.5 [KCrashBackend]
-- Information about the crash:
KDiff3 is using default configuration, and is started using "git mergetool"
After fixing the merge conflict, I want to delete some duplicate lines.
Selecting the lines works (using shift+down keys), but on pressing the
delete-key KDiff3 crashes.
The crash can be reproduced every time. (tried three times)
-- Backtrace:
Application: KDiff3 (kdiff3), signal: Aborted
