Code below.

Trying to return contents of media folder to create gallery. Sample code below works, but ONLY on some media folders!

PLEASE examine the basic folder structure in my media section. Notice that any FOLDER with an "id" greater than 1500 works and the images are returned by the code below. ANY FOLDER with an "id" lower than "1500" does not return anything in the for/next loop. The LOOP is not entered, as even plain text nested in the loop is NOT displayed.  In reality the "cutoff" id does not appear to actually be 1500, as I think a media folder with 1496 also works. But clearly "old" vs "newer" media is making a difference. The "newer" media folders in my tree return data via the XSLT, the older media folders do not. I looked in the DB and see nothing odd between the different media folder id rows. 

Am I doing something wrong, or is this a huge bug?
