@idbrii No, nothing like that. Also, true to the Debian spirit, apt delivers a two years old version, multiple stable releases behind. I built from source.
The errors sit some levels deep the plugins LUA stack. I'm not a big fan of LUA, so the prospect of "debugging" this kind of stuff doesn't excite me very much. Especially if it's a challenge already to figure out WHERE THE F the plugin manager stores the freaking files (it's in ~/.local/share/nvim/).
