I hit this problem too. When DVD Decrypter tries to write to my NAS share via ~/.gvfs, it keeps complaining that there's no space available. If I mount the share with "mount -t cifs", DVD Decrypter detects the amount of free space correctly. It is possible to copy files via ~/.gvfs, but this bug should be fixed, so that applications can correctly determine the amount of free space on the shared filesystem.
