Subject: Emacs hangs when scrolling using gnus-summary-next-page on pages with
	images
Date: Wed, 01 Sep 2010 02:25:16 +0200

Hi,
I'm using gnus with the new gwene service to read RSS, in particular
webcomics. I've had emacs hang in a particularly bad way when scrolling
pages: consuming 100% of CPU and becoming unresponsive.

This bug should be reproducible with any large images. I tested it with
gwene.com.phdcomics and gwene.fr.lemonde.blog.vidberg.

I'm using (not 100% sure which are relevant)
(setq mm-inline-text-html-with-images t)
(setq mm-attachment-override-types '("image/.*"))
(setq w3m-default-display-inline-images t)
(setq w3m-toggle-inline-images-permanently nil)

with latest bzr emacs and CVS emacs-w3m.

Also a bug but far less major, SPC ignores images in the article buffer,
and consequently the scrolling with large images is weird. It's better
(although not perfect) using the standard emacs scrolling commands (C-v
M-v, etc)

Antoine

In the latest Gnus/Emacs with the new HTML rendering code, this should
no longer be a problem.  And if your Emacs 24 is built with imagemagick
support. images will be scaled down to 90% of the window size, which
fixes some of the scrolling issues.

Nope, still hangs with latest bzr. Also, it seems there's a (require
'browse-url) that's missing somewhere (it complains whenever I open a
news, and evaling the require makes it go away).

That's without imagemagick, I couldn't figure out how to enable it (it
says "no" in configure, although I've got the lib installed, and
--with-imagemagick doesn't change anything).

`(setq debug-on-error t)', repeat the bug and mail me the resulting
backtrace.

apt-get install libmagick++-dev

The thing is, it doesn't crash, it just hangs, so I can't get a
backtrace. If you're talking about the require bug, here it is

Ah, true, thanks. It doesn't appear to change anything though.

Try (setq debug-on-quit t).
