Cannot open Deja-dup backup program

Description

Deja-dup gives "could not implement mount" error whenever I try to open it; this happens with the Live USB as well, so it's not just a problem with my installation. Note that this happens before getting prompted to do anything with the program. All packages are up-to-date.
