Although Filelight had the option "Scan across fliesystem boundaries" unchecked, it scanned also sshfs mounted a filesystem in my home directory. $ mount | grep sshfs sshfs#ritter:/ on /home/eddy/mnt/ritter type fuse (rw,nosuid,nodev,max_read=65536,user=eddy)
I confirm the sshfs problem, but also, the sysfs is mis-recursed into as well.
