Comment (by vloodo@…):

 I get this error every time I start screen after a recent update. I'm
 using zsh and I've narrowed it down to either something in my .zshrc or
 oh-my-zsh. However, something definitely changed in the screen code base,
 since this started happening right after an update to screen, with no
 other changes on my machine.
