hi all;

void JustDied(Unit * killer)
   {
       Group * killerGroup = ((Player *)killer)->GetGroup();
       if (killerGroup)
       {
           DoScriptText(SAY_CONGRULATIONS, m_creature, killer);
           for(GroupReference * itr = killerGroup->GetFirstMember(); itr != NULL; itr = itr->next())
           {
               Player * receiver = itr->getSource();
               // possible fix crash i think
               if (!receiver)
                   continue;

               if (receiver)
               {
                   // Item bla_bla_bla
                   int32 count = 1;
                   uint32 itemid = ITEM_BLA_BLA_BLA;

                   //now we can add items
                   uint32 noSpaceForCount = 0;

                   // check space and find places
                   ItemPosCountVec dest;
                   uint8 msg = receiver->CanStoreNewItem(NULL_BAG, NULL_SLOT, dest, itemid, count, &noSpaceForCount);

                   if(count == 0 || dest.empty())
                       continue;

                   Item * item = receiver->StoreNewItem(dest, itemid, true, Item::GenerateItemRandomPropertyId(itemid));
                   if (count > 0 && item)
                       receiver->SendNewItem(item, count, false, true);
                   else
                       continue;
               }
           }
