JetPack Publicize and qtranslate

Hello,

I am using latest versions of Jetpack Publicize and qtranslate on WordPress 4.0. I am a little bit confused on how the two plugins work together. On Facebook and Google+, it works perfectly. On Tumblr, the titles of all languages are concatenated (ex: title_entitle_fr), but the body is fine. On Twitter, the title is fully displayed (<!–:en–>title_en<!–:–><!–:fr–>title_en<!–:–>). On linkedIn, everything is badly displayed (Title: <!–:en–>title_en<!–:–><!–:fr–>title_en<!–:–>, Body: <!–:en–> Lorem ipsum …). Has anybody any clue on how to fix this?

Sincerely.
