VirtueMart 2 and language switcher

[keep]

I have a VirtueMart2 and Joomla 2.5 based multilanguage shop with built in SEF.
Everithyig is well except one thing.
There is a language switcher module on the site. I can change the language without any problem outside of VirtueMart, but if I am on a product detail page or any deeper level in the VirtueMart, the language switcher redirect me to the VirtueMart frontpage of the selected language.
Can I stay on the current category or product detail page but with the other language? Or can I get the URL of the current page with the other languages?
