 This part looks like a possible duplicate of #8822, a.k.a #2077.

 {{{
 [Error] getinfo_helper_dir(): Bug: control.c:1715: getinfo_helper_dir:
 Assertion md->body failed; aborting.
 }}}

 Well, that's bizarre. Since when do we allow a microdescriptor without a
 body? I suppose that must be provoked by a failure to write to the
 microdesc cache.

 I've done a possible fix as branch "bug8795".   I think that 6905c1f60d is
 responsible.
