Tried several png's. Blocks app-doc/devmanual building. Works fine in 6.7.9.9

Works here with:

# wget "http://www.gentoo.org/images/artwork/larry-the-cow-full-udder.svg"
# convert larry-the-cow-full-udder.svg larry-the-cow-full-udder.png

What version of librsvg cairo imagemagick libpng gdk-pixbuf you have?

And if you upgraded to >=media-libs/libpng-1.6 just now,
is `revdep-rebuild --library libpng15.so.15` complete?

[Comment 3 Samuli Suominen (RETIRED) 2013-05-03 08:12:03 UTC]

Hmm. From ChangeLog:

2013-04-16 6.8.5-0 Glenn Randers-Pehrson <glennrp@image...>
Handle benign errors as warnings in the PNG coder.

Added 6.8.5.4 to Portage, please give it a try, reopen this if it still doesn't work with latest version + revdep-rebuilded system

 Converting hangs with this file as well.

 Yep, everything was fine, nothing was rebuilt.

I've updated IM and still no luck, so I'm reopening. Attaching my `emerge --info`…

Graphite-free --info and backtrace

Same here. Backtrace (along with emerge --info) attached to show possible culprits - librsvg, glib or imagemagick itself. All ricing flags explicitly disabled for all three prior to checking.

[Comment 7 Maxim Koltsov (RETIRED) 2013-05-05 06:13:16 UTC]

Fails for me too, 6.8.4.9 and 6.8.5.4.

[Comment 8 Michał Górny 2013-06-23 11:08:49 UTC]

I've got the same problem converting SVG to PDF.

[Comment 9 Samuli Suominen (RETIRED) 2013-06-24 01:51:22 UTC]

6.8.6.1 in Portage; tested multiple conversions with convert and all worked here...

[Comment 10 Nikolaj Šujskij 2013-06-24 05:45:06 UTC]

Nope, still hangs here.

[Comment 11 Nikolaj Šujskij 2013-06-24 09:41:03 UTC]

I've compiled IM 6.8.6-1 manually (tar xf && ./configure && make) and convert there works fine. Weird. Should investigate.

I can't reproduce your results. I've tried plain './configure --with-rsvg' and it still fails. Well, unless you actually tried without rsvg support enabled ;) (--without-rsvg is the default, and imagemagick uses something else to decode SVG then).

> Well, unless you actually tried without rsvg support enabled ;)

As a matter of fact, I did :)

imagemagick-6.8.6.8-glib_check_in_svg.patch

This patch should fix the bug.

@maintainers, please forward the patch upstream. I explained the source of this problem in the dupe bug...

[Comment 16 Samuli Suominen (RETIRED) 2013-08-31 19:23:37 UTC]

Thanks. This is in Portage as 6.8.6.8-r1 and I've reported it to upstream too, using the form in the upstream homepage... Hopefully that's enough...
