Before reporting a bug, please check if it is already known about. Indeed, it may already have been fixed in a later release of ergoemacs-mode, or in the development version. Here is the issues list:

If you are able to, try the latest ergoemacs-mode to see if the problem has already been fixed.

To report a bug please be sure your issue is ergoemacs-mode related. An easy way to do that is to get a clean environment to see if you can reproduce the error. If you can load ergoemacs, then this can be accomplished by Alt+a ergoemacs-clean.

Otherwise, this can be accomplished by

emacs -Q

Then in the *scratch* buffer adding

(setq debug-on-error t) ; Activate debugging
(add-to-list 'load-path "/path/to/ergoemacs/")
(require 'ergoemacs-mode)
(setq ergoemacs-debug t)
(setq ergoemacs-keyboard-layout "us") ; Layout you use.
(setq ergoemacs-theme nil) ; For standard theme.
(ergoemacs-mode 1)

Then type Alt+x eval-buffer.

See if you can reproduce the bug from this empty environment. If you can reproduce the bug this way, that rules out bugs in your personal customizations. Then your bug report should begin by stating that you started Emacs with emacs -Q, followed by the exact sequence of steps for reproducing the bug. If possible, inform us of the exact contents of any file that is needed to reproduce the bug.

When you hit an error, a *Backtrace* buffer will appear on the screen. Save this buffer to a file and attach it to your bug report.

Please report documentation bug too.
