Comment (by weasel):

 The problem with running the tor binary is that it's not obvious what the
 heck it will do.  It's scary very, very scary.

 This failure actually is a prime example -- it tries to do thing it has no
 business doing.  All I want is the expiration date of the id key, yet it
 tries to load secret key material that it doesn't need and shouldn't have.
