	* app/curves.c: preview the curve settings in the image window when
	initializing the tool. This way the new curves behaviour (init with
	last settings) is visible.

	* app/user_install.c: check that strings are non-NULL before passing
	them to strcmp.

	* libgimp/gimpfileselection: do not try to pass a NULL text to
	gtk_entry_set_text, use an empty string instead.
