imagemagick-6.8.6.8-glib_check_in_svg.patch

Since glib-2.35.0 g_type_init() was removed and thus librsvg removed the call as well. Now conversion svg -> png (didn't try any other target formats as I found the bug while installing media-sound/kwave which uses convert from imagemagick to resize and convert images from svgz to png) fails. The convert process hangs and needs to be killed.

Upstream tried to fix this by adding g_type_init() to coders/svg.c [1] but they failed to add a proper check for the glib version.

Please see my attached patch which fixed the problem for me. I didn't report this upstream and would appreciate if you could forward the patch to upstream.

NOTE! You need to have a glib version older than 2.35.0 installed to trigger the error.
