Subject: bug#13756: Selecting deleted gnus-summary-buffer
Date: Mon, 18 Feb 2013 23:50:17 +0200 [thread overview]
Message-ID: <87a9r1er5m.fsf@mail.jurta.org> (raw)
Package: emacs,gnus
Version: 24.3.50
Often selecting a Gnus article from the Gnus summary fails with the error:
Debugger entered--Lisp error: (error "Selecting deleted buffer")
gnus-article-get-xrefs()
run-hooks(gnus-tmp-internal-hook)
apply(run-hooks gnus-tmp-internal-hook)
gnus-run-hooks(gnus-tmp-internal-hook)
gnus-article-prepare-display()
gnus-article-prepare(57082 nil)
gnus-summary-display-article(57082)
gnus-summary-next-article(t nil)
gnus-summary-next-unread-article()
call-interactively(gnus-summary-next-unread-article nil nil)
because in `gnus-article-prepare' the line
(set-buffer gnus-article-buffer)
invalidates the previously live current buffer `gnus-summary-buffer'
to #<killed buffer>.
I've tracked this problem down to revno#111328
that has the following relevant diff parts:
+++ lisp/gnus/ChangeLog 2012-12-25 22:12:59 +0000
+
+ * gnus-art.el (gnus-article-setup-buffer): Make sure that the article
+ buffer always points to the right summary buffer.

that uses a pointer to the buffer instead of the buffer name.
Reverting this commit removes the above error.
I don't know what bug this commit was intended to fix,
so I can't suggest how to resolve this problem.
