Looks like we may be having a similar issue:
In NextGen Gallery 1.3.6, I was able to call nggSlideshowWidget in my Header.php and have my header slideshow work, after the upgrade to NextGen Gallery 1.4.0, the slideshow does not function.
The code in my Header.php that calls the NextGen Gallery slideshow:
<?php if (function_exists("nggSlideshowWidget")) if (get_media_header_url()=="None") {...
