As Bob says, you want to create a new Alias out of the alias file's alis resource, e.g.:

from Carbon.File import FSRef, Alias
from Carbon.Res import *

f = FSRef("/Users/has/a 'broken' Finder alias file")

resfile = FSOpenResFile(f, 1)
data = Get1IndResource('alis', 1).data
CloseResFile(resfile)
alias = Alias(rawdata=data)

To get any useful data out of this 'broken' alias you'll have to get your hands dirty though.

Ditto FSCopyAliasInfo. Unfortunately I don't think Python's Carbon wrappers have been updated much since their creation back in pre-OS X days. You could probably patch up a copy yourself without much trouble; it's a slightly hackish solution, but not that hard to do (I've done it myself and my C's rubbish).
