I think you are calling the following method,

- (void)clearvCardTempForJID:(XMPPJID *)jid  xmppStream:(XMPPStream *)stream

it should be called with two arguments ie JabberId and XmppStream object.You may set those thing wrongly.

[XMPPvCardCoreDataStorage clearvCardTempForJID:urNeededJid:xmppStream];
