When I'm trying to connect to raspberry pi's kodi app trough dlna/upnp I get always this exception.

TypeError: decode() argument 1 must be string, not None

In debug mode I checked the variables and header is empty string (probably empty response?) If I try "easy fix" if not header: continue everything works correct (even discovering the streamer) I have tried ubuntu (18.04) version of pulseaudio-dlna - pulseaudio-dlna/bionic,bionic 0.5.3+git20170406-1 all even the version from master - the result is same kodi version - kodi/unknown,stable,now 2:18.1-1~stretch all from repo http://pipplware.pplware.pt/pipplware/dists/stretch/main/binary raspbian version 9.8 (stretch) Or is it more problem of kodi? (but anyway pulseaudio shouldn't crash just on empty response..)

Got the same problem on ArchLinux. Thanks for the workaround :+1: With both packages: https://aur.archlinux.org/packages/pulseaudio-dlna/ https://aur.archlinux.org/packages/pulseaudio-dlna-python3-git/
