I have managed to track down the issue to these changes betwen two versions of swank-allegro.lisp
(defmethod debugger-info-for-emacs (start end) - (list (debugger-condition-for-emacs) + (list (format-condition-for-emacs) (format-restarts-for-emacs) (backtrace start end)))
(defmethod frame-locals (index) (let ((frame (nth-frame index))) (loop for i from 0 below (debugger:frame-number-vars frame) - collect (list :name (to-string (debugger:frame-var-name frame i)) + collect (list :symbol (debugger:frame-var-name frame i) :id 0 :value-string (to-string (debugger:frame-var-value frame i))))))
If i am not changing the file everything works perfectly yet after applying changes to the function frame-locals slime puts nil's instead of variable names.
And modifying debugger-info-for-emacs effectively disables the debuger ... Ignas Mikalajunas
I have managed to find the cause of the (debugger-info-for-emacs) failing. In documentation it is said: (debugger-info-for-emacs) returns a list (condition-description ...)
condition-description---a string describing the condition that triggered the debugger.
yet debugger-condition-for-emacs -
(defun debugger-condition-for-emacs () (list (safe-condition-message *swank-debugger-condition*) (format nil " [Condition of type ~S]" (type-of *swank-debugger-condition*))))
the function generating condition-description returns a list of two strings ... so it is pretty strange that I was the only one to encounter this problem ... Ignas Mikalajunas

The documentation is out of sync with the implementation. Will fix.

Very strange indeed. Are you sure you don't have a stale .elc file around?
