For some reason, selecting on what pages to show a block from admin doesn't work all the times.

Example, i wanted the breadcrumb module to show only on the gallery(rsgallery2), but selecting the gallery from "Menu Assignment" in mod_breadcrumbs settings worked only for the first page of the gallery, and not for the rest of the pages in gallery.

This is what i have done in the index file of the theme:

<?php if (JRequest::getVar('option')=='com_rsgallery2'){ ?>
   <div id="breadcrumb">
       <jdoc:include type="modules" name="breadcrumb" />
   </div>
<?php } ?>

The module will be printed only on rsgallery2 pages.
