Perhaps it's empty and REMOVE_DUPLICATES doesn't like empty lists? If so, file a bug: REMOVE_DUPLICATES should probably just be a silent no-op if the list is empty.<div>

Use "list_var" instead of "${list_var}"<br><br>${list_var} will only work if it happens to evaluate to the name of a list variable....</blockquote></div><div><br>That was the entire point :)<br><br>list_var isn't a list, it's a variable pointing to a list.
