Title: oae-cleaner reports invalid path

I'm seeing the following in the logs:

```
[2013-03-05T12:02:35.686Z] INFO: oae-cleaner/54637 on Nicolaass-MacBook-Pro.local: Starting clean job. (interval=7200)
directory: /var/folders/b6/kd6b88z9601bxrfsr5jl72tw0000gn/T//oae/uploads

[2013-03-05T12:16:44.539Z] INFO: oae-cleaner/54908 on Nicolaass-MacBook-Pro.local: Starting clean job. (interval=7200)
directory: /var/folders/b6/kd6b88z9601bxrfsr5jl72tw0000gn/T//oae/previews
```

Both paths have a double /. It doesn't seem to be breaking anything, so I'm not sure if it's just the logging that has this issue.
