No such function: nntp-request-accept-article

[Marcin 'Qrczak' Kowalczyk]

When sending nntp articles, Gnus started to show the error from the
subject. The message is sent, but it's not copied to the "sent" folder
and the buffer with the message does not close automatically, showing
the error instead.

There is indeed no such function in Gnus sources. Why didn't it
complain before? How to fix this?

I haven't changed anything in Gnus configuration. I tried some Emacs
package (haskell-mode), but then removed it and it did not help.
