I was using the relatedcontent_get_nodes() function and was getting the error when the function was passed a node that had no relatedcontent nodes. 

warning: asort() expects parameter 1 to be array, null given in /Library/WebServer/Documents/staff-6.15/sites/all/modules/relatedcontent/relatedcontent.module on line 63.

I've made minor improvements to the relatedcontent_get_nodes() function and attached a patch. The improved code ensures that even if there are no relatedcontent nodes an empty array will be returned (instead of NULL).

(revisiting my old issues)

Re-rolled this patch properly. It seems to still be a valid improvement to the function relatedcontent_get_nodes().
