Hello,

If you are experiencing problems with SEF URLs in breadcrumbs navigation in VM 1.1.2, please note that this is caused by VM itself. However, it is very easy to fix:
In file /administrator/components/com_virtuemart/classes/mainframe.class.php find the line 363 and change it from:
$cmsPathway->addItem( $item->name, str_replace('&', '&', basename($item->link)) );
to
$cmsPathway->addItem( $item->name, str_replace('&', '&', $item->link) );

If you don't want to change the code, you can download the patched file here:
Please note that the file works only for VM version 1.1.2!

Best regards,
