Comment 6 for bug 367157

Having a non existing cachedir doesn't seem to the entirely proper solution.

The reason this error occurred was because the package manager tried to read the permission of a folder which turned out not to exist. Not entirely sure if this is classify as a bug, considering it is the result of a somewhat faulty configuration.
