Hmm, that's odd.  I can reproduce the error 100% of the time.
I even tried a clean Emacs checkout on a clean OS install:

0. Install Debian Testing in a VirtualBox VM.
1. apt-get build-dep emacs-lucid
2. git clone https://git.savannah.gnu.org/git/emacs.git
3. cd emacs
4. ./autogen.sh all && ./configure && make
5. ./src/emacs -Q
6. Repeat steps 1-5 from my OP.

I include the details of this Emacs build after my signature.

Another thing I noticed, which I don't remember seeing before:

0. HOME=$(mktemp -d) emacs -Q
1. (setq gnus-select-method '(nnnil)) C-j
2. M-x gnus RET
3. m
4. C-x 4 C-o RET
5. foo C-x C-s

The *Group* buffer now has the following contents:

       1: nndraft:drafts
 K#    0: nndraft:queue

where the text properties at bol of the first group are:

  cursor-sensor-functions (gnus-tool-bar-update)
  face                 gnus-group-mail-1
  gnus-group           "nndraft:drafts"
  gnus-indentation     ""
  gnus-level           1
  gnus-marked          32
  gnus-unread          1

and those at bol of the second group are:

  cursor-sensor-functions (gnus-tool-bar-update)
  face                 gnus-group-news-low-empty
  gnus-group           "nndraft:queue"
  gnus-indentation     ""
  gnus-level           9
  gnus-marked          32
  gnus-unread          0

In Emacs 26, the second group nndraft:queue doesn't appear after saving
the *unsent mail* buffer.  I suspect this seemingly unexpected group has
something to do with nndraft-update-unread-articles choking.

Thanks,
