When performing a select in sqlite with a joined table, an aliased column has a null value

I'm trying to join two tables in sqlite with an alias on one of the columns, but when I alias the column, it returns null.

I've got two tables, like this:

sqlite> SELECT * FROM series;
     _id = 1
    name = Castle
    type = show
     who = dan
disabled = 0

sqlite> SELECT * FROM series_meta;
  meta_id = 1
series_id = 1
meta_name = year
meta_type = int
meta_text =
 meta_int = 2009

Now, I try the following query: SELECT _id, name, type, who, disabled, y.meta_int AS year FROM series LEFT JOIN series_meta AS y ON _id=y.series_id AND y.meta_name="year"; I get:

     _id = 1
    name = Castle
    type = show
     who = dan
disabled = 0
    year =

But if I get rid of the column alias (SELECT _id, name, type, who, disabled, y.meta_int FROM series LEFT JOIN series_meta AS y ON _id=y.series_id AND y.meta_name="year";), I get the expected result:

     _id = 1
    name = Castle
    type = show
     who = dan
disabled = 0
meta_int = 2009

I've tried this with sqlite 3.8.8.2 on Windows 7. I also tried it using python, with the exact same results. Removing the table alias doesn't change anything either.

Is there no way to get this to work with a column alias?
