A possible workaround benvdh suggested to me until this gets fixed:
> Basically what I did was to move the ~/.cache/deja-dup folder to my external harddrive and add a simlink with deja-dup as the link_name in ~./cache.
and
> Another thing that helped was to reduce the time backup's needed to be kept. I changed it from forever to a year. Which reduced the cache to 13GB.
This advice might be helpful to others who share our problems.
