user summary line format not being called with headers

user summary line format not being called with headers

My gnus-user-format-function in gnus-summary-line-format seems to be
called with null headers.

Note the following line that says "Error" from the " *Message-Log*"
buffer:
>No more unread articles (Type n for nnmh:lists.soft.gnus [5])
>
>Retrieving newsgroup: nnmh:lists.soft.gnus...
>Error in summary date () line format: (error Specified time is not representable)
>Fetching headers for nnmh:lists.soft.gnus...
>Fetching headers for nnmh:lists.soft.gnus...done
>Scoring...
>Scoring...done
>Sorting threads...
>Sorting threads...done
>Generating summary...
>Generating summary...done

BTW, the entire header looks like: "[0      0 0 ]" when I print it out.
So, it appears to be an array from somewhere.

This comes from the following user-format:
>"%U%R %6,6uD %5,5N %I%(%[%4L: %-20,20uB%]%) %s\n"

set from gnus-summary-format-hook.  And the gnus-user-format-function-D
is:
>(defun gnus-user-format-function-D (header)
>  "Return a prettified date based on age (uses relevant-date)"
>  (let (date-header)
>    (condition-case err
>	(progn
>	  (setq date-header (mail-header-date header))
>	  (relevant-date (gnus-encode-date date-header)))
>      (error (message "Error in summary date (%s) line format: %s" date-header err) ""))))

and finally, relevant-date is:
>(defun relevant-date (date) "\
>Format DATE based on age from current time
>where date is emacs-time cons (hiword loword) and time is
>Within the day  - hh:mm
>Within the week - ddd
>Within the last six months - MMM DD
>Older than six months - YY MMM"
>  (let* ((time (gnus-time-minus (current-time) date))
>	 (seconds (+ (* (car time) 65536) (cadr time))))
>    (cond ((> seconds 15768000)					; half a year
>	   (format-time-string "%y %b" date))
>	  ((> seconds 604800)						; one week
>	   (format-time-string "%b %e" date))
>	  ((> seconds 86400)						; one day
>	   (format-time-string "%a" date))
>	  (t
>	   (format-time-string "%k:%M" date)))))

and finally the version of gnus:
>Gnus v5.4.55; nntp 5.0; nnmh 1.0

Any ideas?  If no answers are forthcoming, I'll probably slog through
the code.  I just want to see if I'm doing something obvious wrong.
(Like header *will* be passed as a null once, get used to it.)

Quoth the manual:

All the specs allow for inserting user defined specifiers---`u'.  The
next character in the format string should be a letter.  Gnus will call
the function `gnus-user-format-function-'`X', where `X' is the letter
following `%u'.  The function will be passed a single parameter--what
the parameter means depends on what buffer it's being called from.  The
function should return a string, which will be inserted into the buffer
just like information from any other specifier.  This function may also
be called with dummy values, so it should protect against that.
