I tried to write a module using the import export api. When I tried send a header, php complained that output already started. It turns out the minixml library has two php files which have a blank line at the end which are causing this problem. The attached simple patch fixed the problem for me and let me send headers properly.

That's true, and those closing PHP tags should be removed completely.
