Bug Description

Reproduced on Windows XP, Inkscape trunk revision 12904 (before Bug #1270607) and revision 12974.

1. Open File>New>Templates...
2. Select a template in the list..
-> The preview zone is empty (see screenshot).
-> The console shows the following message:

---
(inkscape.exe:2912): glibmm-CRITICAL **:unhandled exception (type Glib::Error) in signal handler:
domain: gdk-pixbuf-error-quark
code : 3
what : Couldn't recognize the image file format for file 'D:\Dev\inkscape-12974\inkscape\share\templates\DVD_cover_regular_300dpi.svg'
---

Additionally, if one selects a procedural template (e.g. Empty page) and then selects a SVG template (A4 Page), the Page size and Page orientation options still show on the preview zone (I suspect it's a consequence of the present bug, and thus don't create a new report for now).

Reproduced with Inkscape 0.91 (64bit MSI installer) on Windows 7.

(64bit MSI package does include the SVG loader for gdk-pixbuf (also listed in loaders.cache), but misses the librsvg DLL, as well as libcroco DLL - both present in the devlibs64)

Packaging issues with librsvg (missing gdk-pixbuf loader) originally tracked in
- Bug #168244 “Image tag does not support SVG documents”
Linux devs decided that the report now tracks the same issue as
- Bug #171795 “Don't rasterize linked SVG with <image>”

--
<opinion>I disagree with Martin Owens assessment (bug #168244 a valid packaging issue, and needs to be tracked separately from the underlying general issue in bug #171795), but won't further triage that report.</opinion>

sorry, I should have been more explicit, my console message was identical to that originally reported by jazzy.
also, the problem is not solved by copying the two files librsvg-2-2.dll and libcroco-0.6-3.dll from the devlibs directory to the Inkscape directory. The console messages still remain.

32bit: no gdk-pixbuf loader for SVG (adding librsvg DLL (+deps) by itself doesn't help)
64bit: has gdk-pixbuf loader for SVG, but misses librsvg DLL (+ deps)

Update for 64bit package:

After copying these two DLLs into the Inkscape program folder:
- http://bazaar.launchpad.net/~inkscape.dev/inkscape-devlibs64/trunk/view/head:/bin/libcroco-0.6-3.dll
- http://bazaar.launchpad.net/~inkscape.dev/inkscape-devlibs64/trunk/view/head:/bin/librsvg-2-2.dll
template preview works, as does linking SVG images via <image> tag.

So as far as I can tell, the SVG gdk-pixbuf loader with 64bit devlibs works as expected, and build-x64.xml needs to be updated to include the missing dependencies of
- http://bazaar.launchpad.net/~inkscape.dev/inkscape-devlibs64/trunk/view/head:/lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-svg.dll

This still needs fixing for CMake.
However a quick check in a 64-bit build of Inkscape 0.92pre3 r15225 shows that simply copying the two DLLs doe *not* fix the issue so further investigation is necessary...
