Incompatibilty with Simple Catch Pro theme

I have made a bi-lingual site with the Simple Catch Pro theme, using qTranslate.
Everything is ok, but not the tagline, wich is displayed only in one language.
The suggested sintax for the tagline ([:it]Description in Italian[:en]Description in English) doesn’t work.

I posted this topic to the theme support forum
(http://catchthemes.com/support-forum/topic/tagline-with-qtranslate/)
The theme’s author answered to let him know if he needs to change anything in the theme.

Thank you
