Ncat segmentation fault with --ssl and --chat

Hello, I just tried the new 5.00 release of Nmap and noticed a segmentation fault in the Ncat tool. Searching for this revealed nothing so I am writing to this list. It appears when I combine the --ssl and --chat option like follows: $ ncat --listen --ssl --chat localhost 10000 I can connect multiple times and chat but as soon as one client disconnects the others receive endless amounts of text like this: <user4> <user4> <user4> <user4> <user4> <user4> <user4> <user4> <user4> <user4> <user4> <user4> <user4> <user4> <user4> <user4> <user4> <user4> If any new connection to the listener is created Ncat exits with a segmentation fault. This does not happen if I omit the --ssl option and this also does not happen if I simulate the chat with: $ ncat --listen --ssl --broker localhost 10000 I tested this on an Ubuntu9.04-amd64 system with kernel 2.6.28 and libssl0.9.8g. If there's any more information you need let me know.
