data.fetcher_assets is empty or null

Hi,

I had been trying to ponder this ordeal with data.fetcher_assets. I am using fetch_csv to grab my data from dropbox with the following code

def initialize(context):  
    fetch_csv('https://dl.dropboxusercontent.com/u/26039084/MEG.csv',  
              date_column = 'DATE',  
              symbol='MEG',  
              date_format='%M/%D/%Y')  

under handle_data all I am trying to do is to get the symbols from data.fetcher_assets but this thing is null!!

def handle_data(context,data):  
    print "total fetchet_assets size:{c}".format(c=len(data.fetcher_assets))  
    for stock in data.fetcher_assets:  
        print "list of stocks:{s}".format(s=stock)

I get the below response

2010-01-06 22:38  PRINT total fetchet_assets size:0  
2010-01-06 22:39  PRINT total fetchet_assets size:0  
2010-01-06 22:40  PRINT total fetchet_assets size:0  
2010-01-06 22:41  PRINT total fetchet_assets size:0  
2010-01-06 22:42  PRINT total fetchet_assets size:0  
2010-01-06 22:43  PRINT total fetchet_assets size:0  
2010-01-06 22:44  PRINT total fetchet_assets size:0  

How can I iterate through data.fetcher_assets to get the fetch stock from fetch_csv()????
