gnus v5.10.2 errors out on newsgroups with quotes (") in them

gnus v5.10.2 errors out on newsgroups with quotes (") in them

[wayne]

After many years of using gnus as just a mail reader, I've recently
started to use the news reader functions again.

One thing I just discovered is that gnus v5.10.2 barfs when it
encounters a newsgroup with a quote (") mark in it.  Now, back when I
used to be a news admin and read news, such charcters weren't allowed
in newsgroup names.  I don't know if this has changed or not.

Anyway, the news server that I use, corp.newsfeeds.com, has several
newsgroups in its active file with quote marks, such as:
alt.i.love.ab"ie.cummings

If I do a "B<cr>nntp<cr>corp.newsfeeds.com" command, it will try and
read and parse the active file.  When it encounters a news group with
a quote, it gets confused and errors out in
gnus-browse-foreign-server.

I can "fix" this problem by deleting groups with quotes in them via the
gnus-ignored-newsgroups variable.

The following is the traceback that I get:

Nope, they aren't allowed.

Sigh, newsfeeds.com is one of those places that boast about
"uncensored" newsfeeds -- nevermind that their active file is full of
garbage and invalid group names.

When you get the backtrace could you switch to the " *nntpd*" buffer
(note the leading space) and copy a couple of lines from the active
file around the offending group.
