If you use next_post_link('%link', '%title', true) or previous_post_link('%link', '%title', true) to get the adjacent post for a custom post type which has a taxonomy assigned to it, it doesn't work as intended.

Those functions are all hardcoded to look to the taxonomy 'category'. This patch let's you change that if you'd like.

If you have a custom post type 'product' with a taxonomy 'color' and want the prev/next post links on the single product page to go to similarly colored ones, use this:

be_previous_post_link('%link', '%title', true, '', 'color'); be_next_post_link('%link', '%title', true, '', 'color');

Please post any issues you find on the Trac ticket so the core patch can be updated: http://core.trac.wordpress.org/ticket/17807
