I can confirm that this bug also appears when connecting to a Windows file server. However, in retrospect to #9, at file copy no error is thrown, but it silently overrides the alteration and created timestamps with the current time as in #5.
The problem perseveres both with
$gvfs-copy --preserve Test.txt smb://server/share/folderX/Y/Z/.
and
$cp --preserve=timestamp Test.txt /run/user/1000/gvfs/smb-share\:server\,share\=share/folderX/Y/Z/
