Summary: current ruby 1.8.2 cvs has inconsistent string handling (null char in string error)

Initial Comment:
Here are the info:
16:46 > cat foo.rb 
    def self.search_loadpath(file)
p file
      result = Dir.glob("{#{($LOAD_PATH).join(',')}}/#{file}{,.rb,.so}")
      p result
      result.delete_if {|f|  p f;File.directory?(f)}.size > 0
      result
    end
search_loadpath("openssl.so")
16:46 > ruby foo.rb 
"openssl.so"
["/sb/tb/toolbox3/sparc-sun-solaris2.5.1/lib/ruby/1.8/sparc-solaris2.8/openssl.so"]
"/sb/tb/toolbox3/sparc-sun-solaris2.5.1/lib/ruby/1.8/sparc-solaris2.8/openssl.so"
foo.rb:5:in `directory?': string contains null byte (ArgumentError)
        from foo.rb:5:in `search_loadpath'
        from foo.rb:5:in `delete_if'
        from foo.rb:5:in `search_loadpath'
        from foo.rb:8
16:46 > ruby -v
ruby 1.8.2 (2004-11-24) [sparc-solaris2.8]

with a little bit debugging added to string.c
I get
"openssl.so"
["/sb/tb/toolbox3/sparc-sun-solaris2.5.1/lib/ruby/1.8/sparc-solaris2.8/openssl.so"]
"/sb/tb/toolbox3/sparc-sun-solaris2.5.1/lib/ruby/1.8/sparc-solaris2.8/openssl.so"
string is /sb/tb/toolbox3/sparc-sun-solaris2.5.1/lib/ruby/1.8/sparc-solaris2.8/openssl.so.so 79 != 82
foo.rb:5:in `directory?': string contains null byte (ArgumentError)
        from foo.rb:5:in `search_loadpath'
        from foo.rb:5:in `delete_if'
        from foo.rb:5:in `search_loadpath'
        from foo.rb:8
