Segfault when saturate_and_pixelate-ing a Gdk::Pixbuf

[phan <phanyx o2 pl>]

Hello,

I have a Gdk::Pixbuf created by Gdk::Pixbuf::create_from_inline() method (that is, an image itself is created by gdk-pixbuf-csource utility), and I get a segfault, when trying to saturate_and_pixelate() it. Here's the code:

	// raw_pixbuf is the csource image
	Glib::RefPtr<Gdk::Pixbuf> pixbuf = Gdk::Pixbuf::create_from_inline (-1, raw_pixbuf);
	if (pixbuf)
		pixbuf->saturate_and_pixelate (pixbuf, 0.0, false); // <-- segfault here.

I've also tried sth like this:
	Glib::RefPtr<Gdk::Pixbuf> pixbuf = Gdk::Pixbuf::create_from_inline (-1, raw_pixbuf);
	Glib::RefPtr<Gdk::Pixbuf> dest_pixbuf = Gdk::Pixbuf::create_from_inline (-1, raw_pixbuf);
	if (pixbuf && dest_pixbuf)
		pixbuf->saturate_and_pixelate (dest_pixbuf, 0.0, false);
but it gives me segfault in the same place.

I've tried to manipulate the arguments of the method and it works, when I pass sth like: saturate_and_pixelate (pixbuf, 1.0, false), i.e. "do nothing with the pixbuf". Any other arguments gives segfault.

The pixbuf itself is working - I can successfully use it as a Gtk::StatusIcon. Just the saturate_and_pixelate() part doesn't work. What am I doing wrong?
