That error is coming from somewhere in the code below, which could
actually be quite a bit of code since it is calling out to
`nnmail-split-incoming' which is a fairly large function. Have you
changed anything configuration related to mail splitting recently?

One thing you can try, to get a better traceback, is find this code in
the source file (nnmail.el:1828) and change the `condition-case' to
`condition-case-unless-debug'. Then M-x toggle-debug-on-error, and run
the code again, and paste the traceback you get from that.

(condition-case cond
    (mail-source-fetch
     source
     (let ((smsym (intern (format "%s-save-mail" method)))
	   (ansym (intern (format "%s-active-number" method)))
	   (src source))
       (lambda (file orig-file)
	 (nnmail-split-incoming
	  file smsym
	  spool-func
	  (or in-group
	      (if (equal file orig-file)
		  nil
		(nnmail-get-split-group orig-file
					src)))
	  ansym))))
  ((error quit)
   (message "Mail source %s failed: %s" source cond)
   0))
