Comment(by duncan):

 I suppose we could improve the error message but I don't see that we can
 make anything work if getAppUserDataDirectory fails. It means we cannot
 read the config file.

 The error message issue could do with some work. We should make sure the
 topHandler is not throwing useful information away.
