tree_view fails on creating a drag icon; bug 63191

[Detlef Reichl <detlef reichl arcormail de>]

in gtk_tree_view_create_row_drag_icon() the icon creation fail, cause
gtk_tree_view_column_cell_render() is called with expose_area == NUL

to fix this the call has to be:

gtk_tree_view_column_cell_render (column,
				  drawable,
				  &background_area,
				  &cell_area,
				  &cell_area,
				  0);

have a nice day
