The Gnus manual instructs users to put a call to
`gnus-group-split-setup' in their gnus.el file if they want to skip over
some tedious manual configuration.
The problem with this is that the function has:
(gnus-group-split-update)
(when auto-update
(add-hook 'nnmail-pre-get-new-mail-hook 'gnus-group-split-update))
Meaning that `gnus-group-split-update' is called immediately when this
function is run, which happens before Gnus is done starting up.
split-update calls `gnus-group-split-fancy' which ends up accessing
group parameters on all Gnus groups. Parameter access only works when
gnus-newsrc-hashtb is already initialized. When the hashtb was an
obarray, this process was a silent no-op. Now that they're hashtables,
it signals a type error.
I think a simple solution would be to change the above to:
(add-hook (if auto-update
'nnmail-pre-get-new-mail-hook
'gnus-started-hook)
'gnus-group-split-update)
Ie, if auto-update isn't passed, only run the update once, at start time.

I think that makes sense -- if it doesn't have to be called from
nnmail-pre-get-new-mail-hook; I'm not too familiar with that code.

I think the idea is that if `auto-update' is nil, the update should only
happen once, at start-up time. If it's t, it should happen every time
before we check new mail (which will include start-up time, I think).
Anyway, let me make sure this solves the user's error first.

Okay, I've heard back from the user. I think the proper solution is:
(add-hook (if auto-update
'gnus-get-top-new-news-hook
'gnus-read-newsrc-el-hook)
#'gnus-group-split-update)
The reasoning being:
The original 'nnmail-pre-get-new-mail-hook runs for all mail backends
*except* nnimap, so the update won't fire if the user only has nnimap
backends. 'gnus-get-top-new-news-hook should do just as well.
Originally I put the non-auto-update on the 'gnus-started-hook, but that
means the update happens *after* the first check for mail, which isn't
ideal. There's also the 'gnus-startup-hook, but that happens before the
newsrc-hashtb is built, so we'd get the same error.
'gnus-read-newsrc-el-hook seems to be the only hook that runs after the
hash table is built, but before new news is fetched.
WDYT?
