OS: macOS 10.12.6 64bit
XnView opened in Thumbnails+Filenames view. From the right of thumbs there is Treeview.
I clicked on empty folder in treeview, dragged it into folder with files (JPGs) - green plus appears meaning we're gonna copy folder, not move - released folder, and then XnView crashed.
- Open thumbnails view;
- In treeview drag one empty folder into another (copy);
- XnView crashed;
Expected behaviour: Copy one folder into another
Please, check attached logs
