	* app/core/gimpscanconvert.c (gimp_scan_convert_free)
	(gimp_scan_convert_finish): plugged memleaks and added some sanity
	checks.

	* app/base/pixel-region.c
	* app/core/gimpdrawable-preview.c: removed trailing whitespace.

	* app/tools/gimpdrawtool.c (gimp_draw_tool_on_vectors_curve):
	gimp_stroke_nearest_point_get() doesn't set cur_pos when there are
	no strokes; don't use the uninitialized variable.
