what env can be usefull as well?

from libxml-ruby.

Thanks for the test. I just pushed it to https://github.com/xml4r/libxml-ruby, and it seems to pass without issue.

Can you try with libxml-ruby-2.0.2?

Also, note I've moved all my development over to the xml4r repository...

from libxml-ruby.

This has been fixed - so closing this issue.

Thanks for the report.
