Warning: Creating default object from empty value

On the front end. My default home page is a flexicontent item.
So this is what I just notice right now,

If I type the address directly I get this NOTICE,

PHP Notice: Undefined index: HTTP_REFERER in /home/jdc/workspace/giroambiente/components/com_flexicontent/models/item.php on line 66


Which is looking for the former page and this happens when I am on one of the links like "Servicios" or "Proyectos" and click on the home page.

[error] [client 192.168.0.101] PHP Warning: Creating default object from empty value in /home/jdc/workspace/giroambiente/components/com_flexicontent/classes/flexicontent.fields.php on line 856, referer: giroambiente.prueba.com/index.php/servicios



The varible $field->name prints the name of the custom field I just created called "Fotos"

about
HTTP_REFERER this has been fixed in a later revision

about
Creating default object from empty value ...
what type is the field?
you have added it in a template position or you you output it by using getFieldDisplay() function?

It is a gallery flashmatic type. I added it to my custom template called primera, in the description zone.
This template is a copy of the default template.

Please install the new build that i will make and if the message persists send me a PM
