It must have been introduced lately, since I updated today and last week build worked.

Hey,
it's pretty unusual for a plugin to crash vim/neovim.

I just tried reproducing this by reinstalling newest neovim and opening .tmux.conf but it didn't crash (in fact all was just fine).

Care to link me your .tmux.conf so I can try which specific tmux command / word causes this?

If the bug still persists and we discover what's causing it, it's likely we'll just end up reporting it to neovim project.

Yeah sure, here it is https://github.com/cHoco/dotFiles/blob/master/tmux.conf but I don't think it's related to it since even with an empty tmux.conf just opening it makes nvim crash :(

The crash only happens when opening with neovim, vim works flawlessly.
Later this week I'll try to narrow it down better, but right now I'm quite busy so I just wanted to report it and see if anyone else was able to reproduce it :)

Thanks. Yea, I used your tmux.conf and nvim ~/.tmux.conf doesn't crash :/

Let's wait to see if someone else experiences this or we can get more info somehow.

Hi, I had to reset my machine for other reason and after reinstalling everything this issue seem to be gone. Will reopen if I discover anything :) Thank you for he awesome plugin!

All right. Must've been neovim hiccup or something.
Do report if you find a problem again.
