Hello, I've recently upgraded Ubuntu and Gnus is now failing to parse my
.newsrc.

gnus-version says Gnus v5.13
emacs-version says GNU Emacs 24.3.1 (x86_64-pc-linux-gnu, GTK+ Version
3.8.6) of 2014-01-03 on gold, modified by Debian

I use Gnus with nnimap and nnrss. Here's a snippet of my .newsrc:

These are all IMAP folders (Gmail "tags"). When Gnus starts I'm getting
messages like these:

if: Wrong type argument: symbolp, [Gmail]

It looks like the gnus-newsrc-to-gnus-format function isn't parsing spaces
in the group names, eg. it reads "Deleted", then checks if it's subscribed
by comparing the next character " " to ":", which is false, then it starts
looking for ranges. Since "Messages" isn't a valid range, it gives the
"Mangled line" error. I tried removing a space from a call to
"skip-chars-forward", but there's a call "(read buf)" which still stops at
the space.

I don't mind getting my hands dirty with this, but my knowledge of Emacs
Lisp isn't great.

As for the "Wrong type argument", I tried removing the "[Gmail]:" line but
it made no difference.

Has anyone seen issues like this before?

Thanks,
Chris
