You are right, it may be a problem with presentations.  Looking at the
startup messages, I see the following:

;; loading #P"/var/cache/common-lisp-controller/1000/sbcl/swank/fasl/sbcl-0.9.16-linux-x86/swank-presentations.fasl"
;; loading #P"/var/cache/common-lisp-controller/1000/sbcl/swank/fasl/sbcl-0.9.16-linux-x86/swank-presentation-streams.fasl"
WARNING: change in instance length of class PRETTY-STREAM:
  current length: 25
  new length: 27
STYLE-WARNING: redefining MAKE-PRETTY-STREAM in DEFUN
STYLE-WARNING: redefining MAYBE-OUTPUT in DEFUN
STYLE-WARNING: redefining OUTPUT-LINE in DEFUN
STYLE-WARNING: redefining OUTPUT-PARTIAL-LINE in DEFUN
STYLE-WARNING: redefining FORCE-PRETTY-OUTPUT in DEFUN

which indicates some problem.  Could you tell me how to switch off
presentations?

Thank you,
Nicolas
