this is an old thread but in gnome bug reports it is a recent open issue so it may be of some use to anyone searching for hours for a solution to fix gvfs-fuser issues - which all seem to be tightly related.

I encountered the gvfs-fuser issue attempting to use meld/diff/kdiff over ftp. Seems the problem is between fuser and gvfs. The problem seems not to occur in 3.15.1 but begins being reported in 3.15.2.(the new python ver?) Solution is a workaround not a fix - files/directories will copy but error is still displayed.

Salute Christopher for definingChristopher's answer defines the problem and providingprovides the SOLUTION: https://unix.stackexchange.com/a/77457solution.

All other solutions, related bug reports,Another possible solution is using sshfs (see this comment and versions of the gvfs-fuser bug are HERE due to rulesthis thread). For more information on 2+ links from newer members (though it seems logical to want newbies to post supporting links since often newbie questions are vague although problems newbies encounter are common throughout the web..gvfs-commands, see What is the difference between gvfs commands and common commands like cat, ls, cp?

Possibly-related bugs include GNOME #317875 and GNOME #768281.)
