I'm completely baffled. All 1088 of the cutom posts return true for
has_post_thumbnail and get_post_thumbnail_id returns the correct id.

But for about 600 of them get_the_post_thumbnail returns blank.

Any pointers or ideas would be very much appreciated :-|



PS. clarifying the below: On the custom post's editing screen the featured
image doesn't show in the meta box. But the fact that the 'use as featured
image' link is missing from the image in the media gallery tab seems to
sugest the right image is set as featured but the image is somehow
