Only variables should be passed by reference in finder.module on line 812.

Hi,

This error pops-up as a strict warning whenever I do a search, probably due to PHP 5.4 & Drupal 6 combination. It does not effect the module's functions in any way, but it is a bit annoying. The only thing that needs to be changed is line 812, where:

$finder_element_id = end(array_keys($keywords));

should be changed to something like:

$a_keys = array_keys($keywords);
$finder_element_id = end($a_keys);

Works fine for me...

Best,

Ondrej
