"Notify Me" breaks in 2.0.8e if product detail assigned to a menu item

[conurus]

"Notify Me" breaks in 2.0.8e and bring back the front page IF the product involved has been assigned to a Joomla menu item, "VirtueMart » Product Details Layout"

I can hack around by modifying components/com_virtuemart/router.php, line 156, function virtuemartBuildRoute(&$query), switch case 'productdetails', change that line from

Code Select Expand

if (!count($query)) return $segments;

to

Code Select Expand

return $segments;

The Notify Me URL in 2.0.8e is

Code Select Expand

http://<site>/<menu alias>/notify

which is wrong. After the above hack, it is changed to

Code Select Expand

http://<site>/<menu alias>?layout=notify
