Apparentely stragne debbugnig messages

[Enrico Pirani]

Hello,

I am getting this "strange" debugging messages. For example when I try to 
evalutate this lisp expression

(quattro atomi della coscienza)

I have this 

Debugger entered--Lisp error: (scan-error "Containing expression ends 
prematurely" 44312 44312)
  scan-sexps(44313 -1)
  forward-sexp(-1)

Instead of :

 Debugger entered--Lisp error: (void-function this)
       (this is an unquoted list)
       eval((this is an unquoted list))
       eval-last-sexp-1(nil)
       eval-last-sexp(nil)
       call-interactively(eval-last-sexp)

I am asking you if this is a normal behaviour of the debugger. Thanks
