Trying to get property of non-object

i modified the line from:
$links = _relatedlinks_get_discovered_links($node, $tracker->keywords);
to
$links = _relatedlinks_get_discovered_links($node, $tracker?$tracker->keywords:null);

i don't know if it's correct but i don't have the error anymore

however, it didn't shows me any similar object

I had the same notice after installing kcfinder and inserting images in pages with wysiwyg & ckeditor.
'Trying to get property of non-object in locale_language_url_rewrite_url()'
I read elsewhere that this comes from the url() function that needs a language object.

To remove that notice, I changed the kcfinder_library_path_url() function as follows :

from

function kcfinder_library_path_url() {
	return url(variable_get('kcfinder_library_path'), array('absolute' => TRUE, 'language' => FALSE));
}

to

function kcfinder_library_path_url() {
	return url(variable_get('kcfinder_library_path'), array('absolute' => TRUE));
}

and the notice disappeared.

@madri2, have you tried : $links = _relatedlinks_get_discovered_links($node, isset($tracker->keywords) ? $tracker->keywords : null); ?

i tried :
$links = _relatedlinks_get_discovered_links($node, $tracker?$tracker->keywords:null);
which is almost the same and it seems to work

Thanks for the report. This has been fixed.
