There is a missing string in the po file for marketpress

The little shopping cart on the top right corner shows the text "visit cart", when the mouse hovers over it.
The HTML is:
<span class="view-cart"> - View Cart</span>
I cannot find this string in the PO file for marketpress. If you could add it, I will be happy to translate it for German and re-upload my translations to your translation repository.

Cheers and thanks,
Boris
