v1.7.2 breaks the whole shop page

Hi there,

I just bumped into a bug with the v1.7.2 update. It breaks the whole shop page (and breaks all of my other sites).

As you can see in the screencast: before update, after update, deactivated stage (if I deactivate it, the site works.

The only workaround now was that I luckily had an older version (1.6.3) on another site, and I copied the plugin folder overwriting its folder on this site. So it is back using v1.6.3. However, all of my other sites broke down and had to be overwritten with the older version of DC (v1.6.3).

Kind regards
