URL problem with WP-Ideas plugin

Hi,

I use wp-ideas in my site. Ex:
http://criacaolivre.com.br/is/all-ideas/?galeria=38

The problem is when I use transposh, it changes the URL to:
http://criacaolivre.com.br/all-ideas/?galeria=38&lang=en

The correct URL should be:
http://criacaolivre.com.br/is/all-ideas/?galeria=38&lang=en (works fine)

I guess the transposh confuse “is”, thinking that is a language and cut it. But /is means “idea stream”, and the wp-ideas need this to work.

The other site sections are ok like: http://criacaolivre.com.br/wiki/

How can I fix this problem ?

I need transposh dont remove /is from url.
