Bug in ruby? incompatible character encodings: US-ASCII and ASCII-8BIT

[Brian <briaar () gmail com>]

Using: http://updates.metasploit.com/data/releases/framework-3.5.1-linux-x86_64.run
on a fresh 64 bit ubuntu 10.04 server.

Have tested w/ multiple browsers (IE + Chrome).

I have confirmed this exploit works fine on my local 32bit dev vm.
