But:

alex@pandora:~$ irb
irb(main):001:0> require 'stringio'
=> true
irb(main):002:0> input = StringIO.new("myname")
=> #<StringIO:0xb7a42864>
irb(main):003:0> $stdin = input
=> #<StringIO:0xb7a42864>
/usr/lib/ruby/1.8/irb/input-method.rb:97: [BUG] Segmentation fault
ruby 1.8.4 (2005-12-24) [i486-linux]

Aborted


This is on Ubuntu Breezy.  Any idea why that happens?
