translation doesn't work after extension installation

[czytom]

I can't display any translated article/page. I see strange sql queries like this:

   SELECT `pages`.* FROM `pages` INNER JOIN page_translations on page_translations.page_id = pages.id WHERE ((virtual = 0) and (status_id = 100)) AND ((page_translations.locale = '--- :en\n') AND (`pages`.parent_id = 4)) ORDER BY published_at DESC, pages.virtual DESC LIMIT 1

After some investigation I managed to work around this issue by editing file lib/globalize2/page_extensions.rb and adding .to_s in two places where find queries are created

I've also have problems with conversion symbol to string, but it's already posted as an issue
