I get the same error as you (see below), and I am using the same oracle version. It appears from the error log that it is expecting a character data LOB instead of a BLOB, and blows up when it gets to that.

I don't know much about sql*loader so I can't help you with a work-around from that end, but have you tried using dbms_lob from sql plus, such as dbms_lob.loadfromfile ? That works fine for me: http://www.oracledba.co.uk/tips/load_lob.htm
