Why should one little error bring the entire gnus-group-get-new-news run
to a halt?

That can happen when not only running `gnus-group-get-new-news'
in a nnrss group if there are funny characters in text to be MIME
encoded. `rfc2047-encode' uses `mm-find-mime-charset-region' to
determine charset that is used to encode text, and expects that
it returns a list of single valid charset. However, as the case
may be, it may return a list containing an invalid charset
(actually `nil') or just a list containing a single `nil'.
(with-temp-buffer
(insert "使用者:Ɩ\271富裕")
(mm-find-mime-charset-region (point-min) (point-max)))
=> (nil iso-2022-jp)
(The result will vary according to the language environment.)
In the most case it returns `utf-8' nowadays, but the `nil'
element in the result means there is a character that cannot be
encoded by any charset. For such a case, I've modified
`rfc2047-encode' so as to use `utf-8' as a last resort (the diff
follows). It is no more than a workaround, i.e. some characters
may be encoded irreversibly, but cannot help it.
