The confliction when use wp_get_object_terms

Hi,
I use wp_get_object_terms in sidebar.php
and I in single.php I use wp_get_object_terms too.

The error happens when I view page,It run ok but the following is still on page:
stdClass Object ( [term_id] => 17 [name] => Paris [slug] => paris [term_group] => 0 [term_taxonomy_id] => 17 [taxonomy] => destination [description] => [parent] => 0 [count] => 21 ) ;

I really don't know that:can we use 2 functions: wp_get_object_terms in a page?

Thanks
