As soon as I type the "e" of "(in-package" in a Lisp mode buffer, SLIME stops with the error message included below, and reissues the error until I delete enough characters to make the string no longer recognizable as a package setting form. I use SLIME CVS sources updated a few hours ago with GNU Emacs 20.7.2 and CMUCL 18e under Debian Woody.
