The changelog says the process filter is disabled[1] but I get the following when I do either a C-c C-l or a C-c C-k.
(error/warning) Error in process filter: (error No such face :foreground)
and execution is aborted prematurely. This suggests that the process filter is not being disabled in xemacs.
This problem persists even after I disable the color-theme.el emacs module and remove my custom.el file.
----------- [1] (slime-restart-inferior-lisp-aux, slime-quit-lisp): Disable the process filter to avoid errors in XEmacs.
