Bug ID: 419284
Summary: KDiff3 crashes when dialogue box cancelled on possibly
binary file warning
Product: kdiff3
Version: 1.8.x
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: application
Assignee: reeves...@gmail.com
Reporter: szots...@gmail.com
Target Milestone: ---
DrKonqui seems unable to reach the REST API therefore I copy the report here
manually.
Application: kdiff3 (1.8.1 (64 bit))
Qt Version: 5.14.1
Frameworks Version: 5.67.0
Operating System: Linux 5.5.7-1-default x86_64
Windowing system: X11
Distribution: openSUSE Tumbleweed
-- Information about the crash:
- What I was doing when the application crashed:
1. Open a three way merge with "--auto" command line option where one of the
files is "possibly binary"
2. KDiff3 shows the following statistics:
Total number of conflicts: 0
Nr of automatically solved conflicts: 0
Nr of unsolved conflicts: 0
3. KDiff3 will refuse to open them and asks whether I want to continue:
Some input files do not seem to be pure text files.
Note that the KDiff3 merge was not meant for binary data.
Continue at your own risk.
4. It says "The merge result has not been saved."
5. Click on "Cancel" and KDiff3 crashes
-- Backtrace:
Application: KDiff3 (kdiff3), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
29 return SYSCALL_CANCEL (poll, fds, nfds, timeout);
