Conflict with Fivestar

I am using a fivestar module to rate nodes. I found that when i set clickable fivestar to appear in teasers and visit "send to a friend" link, after sending the form i get "Your vote has been cleared" message, which is from fivestar module and no mail is sended. For now i set fivestar in teaser to be just passive(user can't rate node from teaser - he must visit the full page view) and sending e/mails is now working, but still it's a bug and needs to be fixed. I don't know if this is a bug in Send module or Fivestar module. I'm not a coder, so I wonu't be looking at this anymore.
