Bug ID: 464260
Summary: Dragging folder into main window diff view crashes
Classification: Applications
Product: kdiff3
Version: 1.10.0
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: application
Assignee: reeves...@gmail.com
Reporter: nyanpas...@tuta.io
Target Milestone: ---
SUMMARY
After kdiff3 1.10.0's "side file tree" rewrite, dragging a folder into a diff
pane crashes KDiff3 completely.
STEPS TO REPRODUCE
1. Open KDiff3 from the app launcher (without any files).
2. Drag any folder from Dolphin into one of the two empty text areas in KDiff3.
OBSERVED RESULT
KDiff3 crashes.
EXPECTED RESULT
KDiff3 loads the folder into one of the diff panes, and enters a directory diff
mode either immediately or upon dragging a second folder. If one side is a file
and one side is a folder, do nothing I suppose?
