>Description:
graphics/gdk-pixbuf2 needs librsvg so applications can load svg icons.

>How-To-Repeat:
Install an application depending on gdk-pixbuf2 which uses svg icons, inkscape for example. Librsvg will not be installed and svg icons will not be shown. Other application will not work correctly or even run.
>Fix:
Add the librsvg buildlink3.mk to the Makefile.

 We can't do that right now because librsvg depends on gdk-pixbuf2 and
 that would introduce a dependency loop.

 I see. Then I recommend to make each package that uses gdk-pixbuf2 and
 have svg icons depend on librvsg, and toolkits like gtk3+.

 adr.

 This sounded a little ambiguous, I mean make gtk3+ depend on librsvg.

 That's easy to do, but I don't understand how it would help - AFAICT
 gtk3 does not have any code to link against librsvg. Can you please
 explain what this would improve and how?

 Thanks,

 Yes, you are right. I'm sorry I got it wrong. I thought the
 gdk-pixbuf2 had the svg loader, but it's in librsvg. I don't
 understand why is it not in gdk-pixbuf2, like the rest. And that's
 why librsvg depends on gdk-pixbuf2, and not the other way, like it
 does already with jpg, png &c.  And all in the same proyect. Crazy
 , crazy little gnome.

 Librsvg has to be added to each package that uses svg icons. These
 are some I tested when adding support for a Huion tablet:

 inkscape
 drawing
 mypaint

 People don't notice it because other applications like gimp has the
 dependency on librsvg already.

 They shouldn't be allowed to link to librsvg if they don't depend on
 it; if they are, that's also a bug.

 Also, add netsurf to the list (see PR 57221, the icon in question is
 an svg image and netsurf doesn't explicitly depend on librsvg)

 For what I see, I'm afraid that the developers of those projects
 just expect pixbuf to load the icon. The mess is because the svg
 loader is not in gdk-pixbuf2, like the rest, but in librsvg. You
 can't make gdk-pixbuf2 depend on librsvg, because librsvg depends
 on gdk-pixbuf2. I checked and freebsd and debian are making inkscape
 depend on librsvg. Note that some applications like mypaint will
 not even launch, and others like azpainter (not in pkgsrc) will
 lose functionality.

 Just in case someone is interested in azpainter: this was another
 issue, I'm not sure  what, but I suspect is related with the icon
 cache.
