Pagination issue in searches

qtranslate Slug 1.1.7 & qtranslate or mqtranslate (last versions).
(Reading setting > Front page displays -> Your latest posts)

After one search, function next_posts_link() correctly links to the url, example: “site.com/en/page/2/?s=e” or “site.com/page/2/?s=e”

But when clic on it not goes to the results page number 2 goes to the posts page (blog) number 2.
