Error detected in debug mode

Hi,

Needed enhancement to run with 4.6 (not tested detailed features) :

I got this error when running debug (enhanced using debug_print_backtrace() to localize mode on an empty dictionnary (just installed and activated) :

The debug log says :

[06-Dec-2016 14:29:40 UTC] PHP Notice: add_shortcode was called incorrectly. Invalid shortcode name: explanatory dictionary. Do not use spaces or reserved characters: & / < > [ ] = Please see Debugging in WordPress for more information. (This message was added in version 4.4.0.) in …/www/…/wp-includes/functions.php on line 3996

With my enhanced version of functions.php with new wp_config.php parameter, I display the debug_print_backtrace(), which tells :
