My CSV file looks like this...

Number, Color, Letter, Sequence, Direction
One, Red, , , Up
Two, Blue, , , Down
Three, Green, Alpha, "A, B, C", West

On import, column delimiter is set to "Comma" and the "Text delimiter" field is 
set to double quotes.  Note the fourth column in the third row: it's a quoted 
comma-delimited list.  Calc is importing each element in the list as a separate 
column rather than importing them all together as a single text value.  In 
addition, it's placing the first double-quote in the same cell as "A" and the 
second double-quote in the cell with "C".  Calc should import the text "A, B, C" 
as a single cell without double-quotes.  It's clearly ignoring the text 
delimiter.

I'll attach screenshots of the import dialog and the resulting CSV in case the 
above description isn't clear.
