Version: (using KDE 4.3.0) Compiler: x86_64 architecture OS: Linux Installed from: Ubuntu Packages The bug is triggered when you try to copy or move a file (or group of) from the local filesystem to a remote host through sftp, using the "copy", or "cut", and "paste" menu items, be it from the context menu or the application menu. Strangely, it does work if you drag and drop the files. To reproduce it, just open two dolphin windows and connect to a remote host through sftp. Then right click on a file on your system and select copy. And then, right click on the window of the remote host and select "paste". Dolphin will complaint about "Access denied to sftp://hostname/path/FILENAME.part" (Dolphin adds a ".part" extension to the file you are dealing with) and the operation will fail. As I mentioned earlier, dragging and dropping the file works. And either method (using menus or dragging and dropping) works on Konqueror. So, Dolphin shouldn't fail when doing this. Please note that this problem only occur going from local to remote. You can successfully use menus to copy or move file from the remote host to local.
