TypeError: fsdecode() takes 1 positional argument but 2 were given with PCA backend

[Xavier Poinsard]

I am using 0.8.11-0ubuntu1ppa1609~ubuntu18.04.1 package and trying to use PCA backend.
Here is the error :
MultiBackend: _put: write to store #0 (pca://backupPortableX-cold)
Writing cold_duplicity-full.20200317T082259Z.vol1.difftar.gpg
