gvfs never worked flawless here. I can copy files from amd to the server 
but if i try to copy an folder with files it error.
With libreoffice i always have to safe an file under an different name 
because it does not let me overwrite on an gvfs samba share.
Afterwards i can delete the old file and rename the new file without errors.
But it makes no difference if i use smb1 or smb2 here.
