MatchTagAlways Python error freezes screen when files are left open for a few minutes

[dvejmz]

I recently updated MatchTagAlways to the latest version in master. After doing this I went on to editing some files in Neovim and left them open for a while. When I came back to any one of those files and tried to move the cursor, the window was frozen and displayed the following error:

Error detected while processing function <SNR>78_HighlightEnclosingTagsIfPossible[12].
.<SNR>78_HighlightEnclosingTags[1]..<SNR>78_GetEnclosingTagLocations[6]..provider#python#Call:                                                                              
line   18: Invalid channel "1"

At this point, no matter what key I pressed on the keyboard, the window would remain frozen showing this error. As soon as I disabled MatchTagAlways in my init.vim, the problem disappeared.

Some info about my environment:

• OS: Fedora 24.1
• Neovim 0.1.7
• MatchTagAlways (master)

My MatchTagAlways config is fairly simple:

let g:mta_use_matchparen_group = 0
let g:mta_filetypes = {
    \ 'html' : 1,
    \ 'xhtml' : 1,
    \ 'xml' : 1,
    \ 'phtml' : 1,
    \ 'php': 1,
    \}

If you need any more info from me, just let me know. Thanks.

That strikes me like a Neovim bug. MTA as a plugin has been stable for years (literally; last commit was 2 years ago). Also, the "channel" stuff is neovim-specific I believe.

You're probably right, this looks like a problem with Neovim's Python bindings. I'll follow this up with them, thank you for your help, really!
