pg_dump segfaults on command-line arguments?

This seems like such a silly thing I'm sure it's been fixed already. It
happens on both machines where I have 7.2.1 installed. It appears to
segfault when receiving any long options it doesn't recognise. Is it a
problem with my libraries or with postgres? OS is Debian 2.2.

Feel free to tell me it's because the system needs an upgrade :)
