+ * io-png.c (gdk_pixbuf__png_image_stop_load): Don't leak info_ptr.
+
+ * io-png.c (gdk_pixbuf__png_image_load): Get rid of unused
+ end_info. Also call png_read_end to check proper ending of the png
+ file and catch text chunks after the image data.

* io-png.c (gdk_pixbuf__png_image_load,
gdk_pixbuf__png_image_begin_load): Make libpng use g_malloc
instead of system malloc.
