      Description

      A SIGSEGV occurs when attempting to connect to an unavailable VNC endpoint and SSH is enabled.
      This is caused by the SSL lock array not being initialized, and when free is called it attempts to destroy the non-existent SSL mutexes.

      Fixed by initializing the lock array to NULL and testing for NULL'ness in the uninit.
