prior to this change validateItem check happened in send method only, implemented on almost all sharers individually. If validate item was not OK, function returned and all sharing process stopped silently. As sharer retained self, there was a memory leak. To avoid a memory leak for this path in code, I decided to add validateItem check to share method too, prior to [self retain].

Now we do not retain self, and this check can be safely removed from the share method.

Just realized, that these two particular sharers have overriden validateItem method, which does not allow a picture without title (or status). So the problem you mentioned can have only those sharers with overriden validateItem method.
