#35 TypeError: can't dup NilClass in ruby 1.9.2-head

[Ablyamit Ablyamitov]

OS: MacOS 10.6.3
Ruby: ruby 1.9.2dev (2010-05-30 revision 28085) [x86_64-darwin10.3.0]
Zip: rubyzip and rubyzip2

I can't create zip archive for files that has russian symbols in name. Example:

Zip::ZipFile.open("Photo079.jpg.zip", Zip::ZipFile::CREATE) do |zipfile|
zipfile.add("Фото079.jpg","Фото079.jpg")
end
This code create broken archive Photo079.jpg.zip:

zipinfo Photo079.jpg.zip
Archive: Photo079.jpg.zip 430629 1
warning [Photo079.jpg.zip]: 4 extra bytes at beginning or within zipfile
(attempting to process anyway)
error [Photo079.jpg.zip]: reported length of central directory is
-4 bytes too long (Atari STZip zipfile? J.H.Holm ZIPSPLIT 1.1
zipfile?). Compensating...
-rw-r--r-- 5.2 unx 431106 t- defN 31-May-10 08:14 Фото079
1 file, 431106 bytes uncompressed, 430505 bytes compressed: 0.1%

note: didn't find end-of-central-dir signature at end of central dir.

If change file name in archive from "Фото079.jpg" to "Photo079.jpg" :

Zip::ZipFile.open("Photo079.jpg.zip", Zip::ZipFile::CREATE) do |zipfile|
zipfile.add("Photo079.jpg","Фото079.jpg")
end

Archive will be created properly.
For compressing directory I using following code:

def create_zip_archive(dirname)
require 'zip/zip'
FileUtils.rm_rf("#{dirname}.zip")
Zip::ZipFile.open("#{dirname}.zip", Zip::ZipFile::CREATE) do |zipfile|
Dir["#{dirname}/*"].each do |file|
zipfile.add(file.sub("#{dirname}/",''),file)
end
end
end

It works only for directories that hasn't files with russian names. Otherwise I get following error:

I tried also rubyzip2 library, but got the same error:
