Error dialog

SUMMARY
When running kdiff3 from the command line it will always fail to immediately open the diff and issue an error dialog saying the second file cannot be opened.

STEPS TO REPRODUCE
1.  Execute kdiff3 from the command line with 2 or 3 file arguments.
2. Observe an error dialog that says "Opening of these files failed:\nfile2.txt"
3. Click 'OK'
4. All files are correctly populated in the file selection dialog.
5. Click 'OK'
6. The files are correctly shown in the diff GUI.

OBSERVED RESULT
The diff is not immediately shown when executed from the command line and you must click through several dialogs to get the diff shown.


EXPECTED RESULT
The diff of the files should be directly shown in the GUI.

Hi - I can't reproduce this on Fedora KDE 41 with KDiff3 version 1.12.0, either the RPM or Flatpak version. Could you please test with that version on your end to see if you still see the issue?

Thanks!

It should be fixed in 1.12.0. 1.11.x had issues with command line use that gave false errors.

Hi,

Yes, it appears to work with 1.12.0! :-)
