 On occasion when I'm doing excessive restarts of Tor (especially when
 triggering it to crash) my state gets to be something that causes Tor
 repeatedly to error:

 Jun 19 13:30:56.799 [warn] router_rebuild_descriptor(): Bug: Couldn't
 generate router descriptor.

 Deleting the state file fixes the issue and, for me at least, using the
 attached state with a new Tor instance causes it to choke this way.

 This issue is infrequent and easy to address, but I'm not sure if this is
 revealing a tor issue we want to address in tor. Feel free to close if
 not.

 The bad state was generated with an old Tor version, but logs the same
 entries with Tor v0.2.2.19-alpha (git-7ca7b6ebdcfb8c42)
