--- Please enter the report below this line. ---
I have manually installed the "deluge" package, which after a chain of
depends, requires python-cffi-backend. However, as can be seen from the
following script, deborphan thinks it's not needed. WTF?
Details:
rbthomas@monk:~$ sudo deborphan -Ps --guess-all --libdevel
main/python python-cffi-backend optional

Description: Foreign Function Interface for Python calling C code - backend
Convenient and reliable way of calling C code from Python.
The aim of this project is to provide a convenient and reliable way of
calling C code from Python. It keeps Python logic in
Python, and minimises the C required. It is able to work at either the
C API or ABI level, unlike most other approaches, that
only support the ABI level.
This package contains the runtime support for pre-built cffi modules.
