EntityMalformedException: Missing bundle property on entity of type node. in entity_extract_ids() (line 7670 of

I am debugging my project with Netbeans 7.3 and xdebug and found that entity information is blank when I added $entity in a watch in this function.

/sites/all/modules/contrib/entity_translation/includes/translation.handler.inc

/**
* @see EntityTranslationHandlerInterface::setEntity()
*/
public function setEntity($entity) {

}

FieldCollectionItemEntity object {
fieldInfo => null
hostEntity => null
hostEntityId => null
hostEntityRevisionId => null
hostEntityType => null
langcode => (string) und
item_id => null
revision_id => null
field_name => (string) field_homepage_lead_slider
default_revision => (bool) true
archived => (bool) false
entityType => (string) field_collection_item
entityInfo => array(24) (
[label] => (string) Field collection item
[label callback] => (string) entity_class_label
[uri callback] => (string) entity_class_uri
[entity class] => (string) FieldCollectionItemEntity
[controller class] => (string) EntityAPIController
[base table] => (string) field_collection_item
[revision table] => (string) field_collection_item_revision
[fieldable] => (bool) true
[redirect] => (bool) false
[entity keys] => array(4) (
[id] => (string) item_id
[revision] => (string) revision_id
[bundle] => (string) field_name
[translations] => (string) translations
)

that may be also a reason. There 3 different field collection with unlimited option. None of those field collection fields are required and I didn't fill out all the field collection fields and that's why their properties may be blank. But I need to know how to ignore those blank fields and save the form with little fields translated.

I can edit and save the content in English language which is a default language setting. I get this error only when I try to translate the content and save it. It was working fine before I enable entity translation.

I went through entity translation module and found that its not passing entity_type property to setEntity function which is fine.

entity_translation.module
function entity_translation_language($entity_type, $entity) {

$langcode = $handler->getLanguage();

//old code
$handler->setEntity($entity);

//I added
// $entity_type = 'field_collection_item'
$handler->setEntity($entity,$entity_type);
}

But when you try to get the entity type in this function
includes/translation.handler.inc

public function setEntity($entity,$entity_type=NULL) {
if($entity_type != NULL){
// I added
$entity_type = 'field_collection_item'
list($this->entityId, , $this->bundle) = entity_extract_ids($entity_type, $this->entity);
}
else
{
// Update bundle and entity id properties.
// old code
$this->entity_type = 'bean'
list($this->entityId, , $this->bundle) = entity_extract_ids($this->entityType, $this->entity);
}
}
After I changed the above code somehow its working but still when you try to add more item with "Add More Item" button for FC then my FC content goes blank and it happens only for translated content. It doesn't happen when you try to edit the English content.

I don't know if I added right code or not.

I have added couple of patches for both ET and FC modules. So there will be problem if I don't use Dev versions of FC and ET and Beans module. Can you recommend which version should I use so that I will try to install fresh D7 installation with ET, FC and Beans module.

Is it safe to use those dev versions of FC, ET for live site ?
