Strange "Search popup" behavior for item's URL

Hi Team,

We are still testing the new 1.2.7 version (actually I found this issue also with 1.2.6 - that we've just bought and installed yesterday) and found a strange issue that maybe something related to SEF.

Environment:
- Joomla 3.2.3
- PHP 5.4.26
- Falang 1.3.2 (latest)
- Offlang Universal AJAX Live Search
- ReDJ (only for 404 page redirection)
- EasySocial 1.2.7

Let me give some explanation:
1) Search a something in the toolbar search box (using Forsty theme)
2) URL for the item (eg: an album) is http://SITEURL/joomla/language/easysocial/joomla/language/easysocial/albums/item/123-albumname/user/234-userid
NOTE: "joomla/language/easysocial/" this part is duplicated ***
3) I have an 404 error when I click it.
4) now I re-do steps 1,2 again, got the same item on screen but I click [View all results]
5) I can see the same item on screen, but this time its URL = http://SITEURL/joomla/joomla/language/easysocial/albums/item/123-albumname/user/234-userid
6) OOOOPPPSSS.... the link also not working...
NOTE: The joomla folder is duplicated (joomla/joomla/)
7) The correct link should be (view the album from user profile directly) :
** I guess there are some SEF issue with the toolbar's search module (maybe while using with falang?)

I confirmed I have no other issue for Joomla searching even using in the extended search component - Universal AJAX Live Search.

Anywhere (configuration/ settings) I should be looking for or this is a issue or conflict with the toolbar search? I am not sure if there is any conflict with my multilingual system - falang. This is the only component have similar issue so far.
