It's current testing. And other versions are mentioned in the bug repport
https://bugs.kde.org/show_bug.cgi?id=434145 I am sorry I didn't mention this before but the problem appears only with Dolphin and Krusader. It has to be something with Kio I think, because there is no problem when copying with MC or cp command.
