Language switch of Modal Popup doesn't work after upgrade to VM 3.0.6

[peterva]

After upgrading to VM 3.0.6, it looks like VM is not handling the language switch for the modal addtocart popup correctly.

This results in the following problems:

• add-to-cart popup is in Dutch (= default language), even if the selected language is English or German
• 'go to cart' link in this popup does not add the language tag to the url (e.g. /en or /de or /fr), so onclick you get 'page not found'

Reproduce this problem:

• go to http://dev.saintbasics.com/en/men/t-shirts/st-marcel-black-xl-detail, this is an English language URL
• select size and click 'add to cart'
• you will see that the language stays in Dutch
• click 'toon winkelwagen' at the top of popup, you will get 'page not found'

This is my development site, Beez template activated (so no styling), but you can check the error.
I cleared the cache on the admin side.

Does anyone else have this problem and more importantly, how can it be fixed?

My config:
Joomla 3.4.0
VM 3.0.6
PHP 5.4.4-14+deb7u5

I cannot reproduce this for j2.5, nor j3.4

It looks like someone has the same problem here:

My problem disappears too when I turn off SEF. Any clues?

Lets discuss there, the reason I cannot reproduce it, it is a j3 problem. I still use j2.5 for development.
