+Subject: [PATCH] image: Don't crash on weird pixman formats
+
+_pixel_to_solid() used to assert that it got a known cairo_format_t.
+However, this might not be the case when backends decide to use a pixman
+format that is not representable by a cairo format (X and DirectFB are
+examples for backends that do that).
+
+This patch makes _pixel_to_solid() return NULL in that case and fixes
+the callers to deal with it.
