Product page title not displayed properly

Seems a bug was introduced in the item template title:

Check title value here:

http://sinkhole-art.com/gods/mojo?variant=TM-G-101-BLACK-M
http://almavivens.com/products/almavivens-classy

Seems a huge hash containing all product attributes is set as the title value. Any clue?

Yeah you are right, could replicate this issue. Can you raise a github issue a well for the same at https://github.com/frappe/erpnext/issues/new

It has been fixed via https://github.com/frappe/frappe/pull/2792. Should be merged soon.
