~/.gvfs folder causes backup error
The Problem is the following: if a user is logged on to the gnome or kde session and makes use of the GVFS layer, the directory ~/.gvfs is created.
This directory cannot be entered by any other user (even root), unfortunately this is not the only problem: the system call "stat" also errors out on this directory.
This is also the reason it can't be excluded, because while creating the file list and looking at the excludes, sbc_find once does a "stat()" call on the directory and receives an error.
Create a new file named /etc/profile.local with the contents below
GVFS_DISABLE_FUSE=1 export GVFS_DISABLE_FUSE
Run the following command for each affected folder
fusermount -u /home/$USER/.gvfs
test with stat /home/$USER/.gvfs
