Yes, I think this was fixed in 5.30BETA1. From http://nmap.org/svn/CHANGELOG:

o Fixed an assertion failure which could occur when connecting to an
  SSL server:
    nsock_core.c:199: socket_count_write_dec: Assertion `(iod->writesd_count) > 0' failed.
  This was observed when running the http-enum script but could
  possibly have happened in other situations. Thanks to Brandon for
  reporting the bug and testing. [David]
