When compiling a code snippet with C-c C-c, I get the following error in SLIME:

It looks like something added text properties to the string returned by buffer-name. Do you use a package like iswitch-buffer that, unintentionally, adds text properties to buffer names?
I am not using iswitch-buffer, but I don't really know much about text properties to allow me to figure out what is adding them, it looks like something triggered by SLIME.
If I start emacs-snapshot, open a .lisp file and eval (buffer-name), I get something like "foo.lisp".
Then, if I start SLIME (ie an inferior lisp), and eval (buffer-name) in the lisp buffer, I get something like
#("foo.lisp" 0 8 (buffer-name #0 buffer #<buffer foo.lisp> font-lock-face buffer-menu-buffer mouse-face highlight help-echo "mouse-2: select this buffer"))
Apparently SLIME is changing something. Suggestions on how I could find what it is would be appreciated, I can reproduce this with a minimal SLIME setup, but only with the latest emacs snapshot. The relevant part of *Messages* is
How recent is your Emacs snapshot? Coincidentally this ChangeLog entry:

* buff-menu.el (Buffer-menu-buffer+size): Remove calls to bidi-string-mark-left-to-right; they are unnecessary now.
probably fixes the problem. bidi-string-mark-left-to-right does normally not copy the string, i.e. does the opposite of what the "Don't put properties on (buffer-name)" comment in buff-menu.el says.
