slapd with wrong url causes "Error detected by libpthread: Invalid mutex"

[Jean-Luc Wasmer <jl+openldap@lists.wasmer.ca>]

Hi,

When slapd is started with an invalid url, it looks like it's trying to 
destroy an uninitialized mutex:

Program received signal SIGABRT, Aborted.
0xbb87dfff in kill () from /usr/lib/libc.so.12

This was triggered by calling slapd with an invalid URLlist argument:

-h 'ldap://127.0.0.1 ldaps://<external ip>'

with no interfaces on the system configured with <external ip>
