I'll look into the segfault. If you created the consumer database with 
slapadd -w then you don't need to specify a csn on the command line. And 
actually if the empty-DN entry was part of the slapcat then you don't 
need -w either since the contextCSN is already there in the data.

Yes, it belongs on the provider. The test configs are used in a number 
of test scripts, and in test019 the consumer is also a cascaded 
provider, which is why that shows up there. It isn't relevant for this 
situation, sorry for the confusion.

Looks like I need to update the slapd(8) manpage and remove sid. Yes, it 
has been dropped.

Yes, I did the same setup for test018 and it worked as well.
