Incompatibility between ergoemacs-mode and pdf-tools

[calliecameron]

With ergoemacs-mode and pdf-tools installed, many actions (such as pressing C-h k or <end>) result in lisp nesting exceeds 'max-lisp-eval-depth', and then all keys get unbound, and Emacs must be forcibly killed. This happens with the current version of ergoemacs-mode in MELPA, but not the older version in MELPA Stable. I am using Emacs 24.5.1 on Linux Mint 17.1, ergoemacs-mode 20150318.1413 from MELPA, and pdf-tools 20150526.55 from MELPA (though the same thing happens with the MELPA Stable version of pdf-tools, too).

Minimal working example: remove your .emacs and .emacs.d, open up Emacs, and evaluate:

(require 'package)
(add-to-list 'package-archives '("melpa" . "http://melpa.milkbox.net/packages/"))

Then interactively install the packages: ergoemacs-mode (from MELPA), pdf-tools.

Then evaluate:

(require 'pdf-tools)
(require 'ergoemacs-mode)
(ergoemacs-mode)

The debugger pops up with lisp nesting exceeds 'max-lisp-eval-depth' and Emacs becomes unresponsive.

The master branch is currently unstable and will soon be replaced. I have re-written most of ergoemacs-mode in the modify-maps-new-engine branch, which is starting to be stable enough to try to replace the current master branch. For now the obvious work around is to use the stable release.

OK, thanks.

This seems to work with the current master branch. I'm unsure if everything else works, but its a start.
