Hi Florian--

Sorry for taking a little while to get to this...

Thanks for this information!  It looks to me like the errors are related
to loading the CRL cache. (in particular, in open_dir() in
src/crlcache.c).  I think i'm now able to reproduce this.

I suspect you have a zero-length file in
/var/cache/dirmngr/crls.d/DIR.txt, is that correct?  can you show me the
output of:

   stat /var/cache/dirmngr/crls.d/DIR.txt

If you move that file out of the way, can you start dirmngr without
it crashing?

   mv /var/cache/dirmngr/crls.d/DIR.txt  /var/cache/dirmngr/crls.d/DIR.txt.bak

If this works, do you have any idea how dirmngr's crlcache got into this
state?  I'm working on a patch now.
