Incorrect canonical link on the manufacturer's page

[Rsn]

Hello!
On the Manufacturer Details page the canonical link is incorrectly formed.
It leads to another page with products from this manufacturer.
Example:
Page:              http://demo.virtuemart.net/manufacturers/istraxx
Canonical link: http://demo.virtuemart.net/manufacturer/istraxx
Please note that these links are different and lead to completely different pages.

It would be good to fix it.
