I'm not seeing anything like that, but I don't build back-meta as a 
module.  It would be helpful if you provide at least a stack backtrace 
for that sigsegv, to help understand where and why it occurred.

One thing that is still missing from that test is that if you build 
back-ldap as a module, you need to load it before opening a back-meta 
database, in order load the requested symbols.  I'm fixing this right now.
