Actually I just looked at the tool, and all it was doing was using telnet to check if a couple daemons were up. And the crash happens only in one out of hundreds of these calls, so it's hard to reproduce.
Since I have the screen shot, how/where can I report this as a known problem? I looked at the bug fixes, but couldn't tell if this has been fixed on 6.4 (-248 version).
