Error: Invalid input data while using findItemsAdvanced

[debunge]

Hello! First, I want to thank you for nice and useful library you a developing.

Second,
I've been using it for simple product search
print FindProducts("pen", "false", "10", "JSON")
and it worked great.
but now I want to specify only one seller and have the following problem:

findItemsAdvanced("pen", itemFilter=[{"Seller":"bld304"}])
'{"findItemsAdvancedResponse":[{"ack":["Failure"],"errorMessage":[{"error":[{"errorId":["10"],"domain":["Marketplace"],"severity":["Error"],"category":["Request"],"message":["Invalid input data specified. Please specify data with appropriate data types."],"subdomain":["MarketplaceCommon"],"parameter":[{"@name":"ORIGINAL_MESSAGE","value":"Data validation warning(line 4, col 19): unexpected element (uri:"http://www.ebay.com/marketplace/search/v1/services", local:"Seller"). Expected elements are <{http://www.ebay.com/marketplace/search/v1/services}paramName>,<{http://www.ebay.com/marketplace/search/v1/services}name>,<{http://www.ebay.com/marketplace/search/v1/services}paramValue>,<{http://www.ebay.com/marketplace/search/v1/services}value>"}]}]}],"version":["1.12.0"],"timestamp":["2012-09-20T21:48:32.098Z"]}]}'

I simply do not understand what's going on here.

You need to use itemFilter=[{'name': 'Seller', 'value': 'bld304'}]
