[wp-hackers] get_posts with both a custom post_type and custom taxonomy

Hi Aaron,

I often have the same problem when I want a custom query. Thing is some
arguments overwrite the others in this function, and your resulting query is
selecting posts with post type = post.

My workaround is to use the query_posts hook to strip out this condition
from the resulting sql whenever I want.

This is an area where Im not sure wether its a bug or an expected behavior.
But I think if you pass the post_type paramater it should respect it no
matter what other paramaters are passed... Any one agree we could open a
ticket for that? To not let other paramaters overwrite the post_type
