Comment 1 for bug 227753

This is what finally worked to get my hard drive back:

All done as root:

umount gvfs-fuse-daemon

Change ownership of backup file generated by SimpleBackup on network drive, and move to another location.

Change group of that network directory from "1000" to root.

remove that directory and all its subdirectories (#rm -r /mnt/network-drive/backup) It had no visible or hidden subdirs, but an ordinary rmdir command kept saying it was not empty.

On my computer (not the network drive), remove .gvfs both in my user home dir, and in root's home directory.

exit root. reboot.

The gnome devs really need to get to work on this issue. A filesystem that can make your computer next to nonfunctional is not a minor bug.
