IPhoto "new album" command returning null album

Question

If I run this script, the result is "album id 0 of application "iPhoto"".
tell application "iPhoto"
set a to new album name "Foo"
return a
end tell
I'm not very experienced with AppleScript, but I believe the id 0 indicates "null" -- if I try to do something with it, like "return name of a", I get an error: "Can't get album id 0".
In contrast, if I do this, the result is "album id 4.294967373E+9 of application "iPhoto"":
tell application "iPhoto"
set a to new album name "Foo"
return album "Foo"
end tell
This seems very simple, but apparently I'm missing something.
(The reason I care is that iPhoto's album names aren't unique identifiers -- if I create a new album, I want to be sure I'm working with that album and not another that happens to have the same name.)

Answer 1

Looks like a bug. Try this as a workaround:
*tell application "iPhoto"*
*new album name "Foo"*
*set A to last album*
*end tell*
