Hi!
I got a probably related error after restarting Gnus, which had been
running for a while. Sorry for the late catch. I have a custom topic
function `gnus-user-format-function-topic-line' that started
complaining:
Debugger entered--Lisp error: (void-variable total-number-of-articles)

gnus-topic-prepare-topic((("comics" visible nil nil)) 2 5 nil nil 1 nil)
The confusing thing here is that the eval lexical environment is
correct. I'm not sure what's happening in the stack. I can reproduce it
with a shorter example:
(defun gnus-user-format-function-topic-line (dummy)
(message "total %s" total-number-of-articles))
(let ((gnus-topic-line-format "%i[ %u&topic-line; ] %v\n"))
(gnus-update-format-specifications nil 'topic))
(let ((gnus-tmp-header nil))
(eval gnus-topic-line-format-spec
'((indentation . " ") (visible . "") (name . "comics") (level . 2) (number-of-groups . 1) (total-number-of-articles . 1))))
I hope that helps track it down.
Thank you
Ted
