Hi Stephen,

Here is my backtrace:

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
   all-completions(nil nil)
   comint-dynamic-simple-complete(nil nil)
   (or (comint-dynamic-simple-complete token-string 
possible-completions) (quote none))
   (let* ((comint-completion-addsuffix nil) (beg-of-line ...) 
(end-of-line ...) (line-buffer ...) (token-string ...) 
(possible-completions ...)) (or (comint-dynamic-simple-complete 
token-string possible-completions) (quote none)))
