I'm running cvs head and using slime-fancy (which includes slime- autodoc).

swank:tokenize-symbol-thoroughly is looking for a package specifier and complains if it sees more than two colons. It thinks it's parsing a symbol but this chunk of code causes it to signal an error when called with the format control string:

(with-slots (n-start n-pairs min-word legal-chars pairs pair-table) db (when verbose (format t "n-start: ~d, n-pairs: ~d, min-word: ~d~%" n-start n-pairs min-word)) (dotimes (i n-pairs)

(NB: this obviously isn't a fully formed sexp, just the the smallest text blob I could reproduce this with...)

To reproduce this, load slime (w/ autodoc or fancy), bring the above four lines up in a lisp buffer and try to C-n to the last line (backtrace below). There's something about the first two lines that's relevant. If you delete either the (with-slots...) or (when verbose...) (or both) this doesn't happen.

More than two colons in ""n-start: ~d, n-pairs: ~d, min-word: ~d~%"" [Condition of type SIMPLE-ERROR]
