[similar check of err later in the code]
Quincey Morris identified your problem, but you can't do this. Methods that
take NSError** are entitled to fill in the error return even if they succeed.
Always check the principal return value (tempDir being nil, here) and _then_
you'll know that the NSError represents the actual description of a problem.
