CSV parse failure

has anyone come up to the problem with csv parsefailure? I tested with a csv file that does not have double qoutes around each cell. But when I try to parse through a csv with double qoutes around each cell i get an error... i.e. "northbound","node1"...

"message" => [
        [0] "\"northbound\",\"node1\",\"\", ...
quote_char has to be a single character String

Noticed the problem... The data in one of the column contains double quotes also. Can be viewed on exel fine but why not here.
