FacebookDialog.ShareDialogBuilder, error: post no longer available

Question

I am using the Facebook sdk to share a link. the post share is well generated, but when i click on post, nothing happened and a toast is displayed: "this post is no longer available, it may have been removed"

it gives me no error, just this toast.

i m using basic code from the sdk:

FacebookDialog shareDialog = new FacebookDialog.ShareDialogBuilder(getActivity())
                    .setLink(mStationLink)
                    .setDescription(mTextToShare)
                    .setPicture(mImageUri)
                    .build();
uiHelper.trackPendingDialogCall(shareDialog.present());

did someone come accross this?

thanks
