ruby-sqlite 2.2.3 bug

[Jon A. Lambert]

This is using sqlite-ruby (2.2.3)

-----------------------
require 'sqlite'
require 'pp'

class Foo
end
db = SQLite:atabase.open("test.sqlite")
begin
db.execute("drop table test;")
rescue
end
db.execute("create table test (id integer primary key, data object);")
db.type_translation = true
db.translator.add_translator("object") {|type, value|
db.class.decode value
}
db.execute("insert into test values (1, ?);", db.class.encode(Foo.new))
db.execute("select * from test;") do |row|
pp row
end
#db.type_translation = false <== uncomment to make work
pp db.execute("pragma table_info(test)") <======= bug here
db.table_info("test") do |row| <===== and here
pp row
end
----------------------

Switching type_translation off allows pragma to work.

Also example in documentation, shows 'db.decode' instead of
'db.class.decode'
