--- Comment #2 from Jens <jens-bugs.kde.org at spamfreemail.de> ---
I can second this, and here is another report: 
https://superuser.com/questions/1814677/files-are-corrupt-after-copying-streaming-them-from-samba-fileshare

Copying using cp, rsync or any other tool on a SMB mount works. Copying via
Dolphin will corrupt the file.

Workaround: add "cache=none" to the SMB server's mount options so that the file
copy process is not cached.
Then, also Dolphin can copy the file without errors. And as an additional bonus
the copying speed doesn't oscillate so much any more.

This is not a fix however. And I think this is quite a serious issue.
How can we help finding the root cause of this?
