UTF-8 error when using Dir.glob with File::FNM_CASEFOLD

I have a line in an application like this (search the given directory for ogg and mp3 files):

Dir.glob "#{ARGV[0]}/**/*.{ogg,mp3}", File::FNM_CASEFOLD

Using Ruby 1.9.3, this raises an error:

test.rb:1:in `glob': invalid byte sequence in UTF-8 (ArgumentError)
         from test.rb:1:in `<main>'

I guess I have a weird file name somewhere. However, if I drop the File::FNM_CASEFOLD, then it works fine.

Is there a way to work around this, or at least not stop the globbing when this occurs? Or am I running into a bug?

Thanks,
Justin
