Since it's working smoothly on my HTPC, I've published kodi-18.5 to the -unstable repo, which means that it'll be part of the next sync.
Should any of you lovely people need to build your own 3rd-party kodi binary plugins, you'll likely be happy to hear that I've also published a safety rebuild of kodi-platform, which is a necessary dependency in that specific scenario.
Fingers crossed that it'll be smooth sailing for you lovely peeps too. 😃
