+Subject: [PATCH] runtime-install: install rsvg-pixbuf-loader
+
+This was split out of librsvg2 as a subpackage recently, and
+is only Recommended by the parent (not Required). For size's
+sake, we don't pull Recommends into the installer env by
+default. But we do really need this package, because quite a
+lot of icons used in the installer are only present as SVGs in
+the installer environment, so if we don't have the SVG loader we
+can't show the icons.
+
+Right now anaconda actually crashes if the SVG renderer isn't
+present, which wasn't an expected outcome, but even if the crash
+is fixed, the result would be that anaconda would run but not
+show a lot of icons, which obviously isn't what we want. So we
+should add this regardless of a fix for the crash.
