sbackup does not complete remote backup; eventually crashes with gnome-vfs-modules-CRITICAL error

Binary package hint: sbackup

v1.3 and v1.4b are not completing the files.tgz file. After only a minute of transfer (e.g,. 30MB out of 1100MB), the tar and ssh processes stop and sbackup remains silent. About half an hour later, it crashes with the following:

(process:21843): gnome-vfs-modules-CRITICAL **: Could not read 1 bytes

(process:21843): gnome-vfs-modules-CRITICAL **: Could not read 4 bytes
