I believe what's happening here is sbcl is dieing on line 109 of swank-loader.lisp:

(defun file-newer-p (new-file old-file)
   "Returns true if NEW-FILE is newer than OLD-FILE."
   (> (file-write-date new-file) (file-write-date old-file))) ;line 109

For some reason sbcl cannot figure out what the file-write-date of
"/home/pupeno/.slime/fasl/sbcl-0.9.13-linux-x86/swank-backend.fasl" is,
so it is returning nil and operator '>' is complaining about a nil argument.

Interestingly enough, this is a known problem (to Google):
