Error writing a file via ssh

[stcz]

I try to sync two directorys one is lokal and the other mounted via gvfs-mount and sftp (ssh). With Nautilus i have read and write acess to all files and folders over "/run/user/1000/gvfs/sftp:host=***,user=***/home/***". Transfairing files from the sftp directory to the local one is working.
From the local to ssh i get the following Error Message:
---------------------------------------------------------------------------------------
Cannot write modification time of "/run/user/1000/gvfs/sftp:host=***,user=***/home/***.ffs_tmp".

Error Code 95: Die Operation wird nicht unterstützt (utimes)
---------------------------------------------------------------------------------------
If i copy the file with Nautilus it works and its possible to write the modifications time.
Both filesystems are ext4.
I'm running Freefilesync 6.6 from ppa:freefilesync/ffs on ubuntu 14.04
But the Error is older, i've had it already on 12.04

That's a bug in gvfs: https://answers.launchpad.net/freefilesync/+question/220745
