Jomsocial activity problem

Hi,
when I create a new discuss a post is added on jomsocial wall but the link has a mistake in the title. When I click on link I go to home page instead to go to discuss.
I checked on db and I found that before the link there are 3 double quote.
Infact if I delete the 2 double quote the link works fine.

Take a look belove

Title
{actor} ha risposto alla discussione <a href="""http://localhost/ivt_30_09/index.php/it/discussioni/efdfdfd#Rispondi-12""">http://localhost/ivt_30_09/index.php/it/discussioni/efdfdfd</a>

Content
fedgdfgd...<div style="text-align: right;"><a href="http://localhost/ivt_30_09/index.php/it/discussioni/efdfdfd">Partecipare alla discussione</a></div>

Same problem if i click Ilike or a post an answer in a discuss.

version of software
Joomla 2.5.9
Jomsocial 2.8
Easydiscuss 3.1.8872

Thanks
