Division by zero error

[lipatovroman]

Hello.
When I trying to edit an item with zero votes, I'm getting Division by zero error.

Also, I'm getting error report on my email:
Error Code 0
Error Type DivisionByZeroError
Message Division by zero
File /var/www/site/data/www/site.com/administrator/components/com_flexicontent/models/parentclassitem.php
Line 4270
Protocol https
Host site.com
Request /administrator/index.php?option=com_flexicontent&task=item.edit&view=item&id=2412
Referrer /administrator/index.php?option=com_flexicontent&view=items
Method GET

This error appears if item have zero votes.
So, I edited _content_rating in database and added 1 votes.
After that it's ok. But it should be fixed
