hp-setup from hplip version 3.19.1 crash when trying to configure a printer (USB connection)
Here is the trace from python:

Traceback (most recent call last):
  File "/usr/bin/hp-setup", line 426, in <module>
    ppds = cups.getSystemPPDs()
  File "/usr/share/hplip/prnt/cups.py", line 329, in getSystemPPDs
    path = os.path.join(cups_ppd_path, ppd)
  File "/usr/lib/python3.6/posixpath.py", line 80, in join
    a = os.fspath(a)

The linux distro I use is Void.
