Game crashes with error as - > onRealTimeMessageSent(Unknown Source)

Question

Did anyone come across this type of error ?? This thing happens after the message is sent succesfully to the other device ..

01-30 14:20:38.894: E/AndroidRuntime(6258): FATAL EXCEPTION: main
01-30 14:20:38.894: E/AndroidRuntime(6258): java.lang.NullPointerException

01-30 14:20:38.894: E/AndroidRuntime(6258): at com.google.android.gms.internal.ex$am.a(Unknown Source)

Code i have used to send message to the others participants :

for (Participant p : mParticipants)
{
    if (p.getParticipantId().equals(mMyId))
        continue;
    if (p.getStatus() != Participant.STATUS_JOINED)
        continue;

    if(p.isConnectedToRoom()) 
    {   
        getGamesClient().sendReliableRealTimeMessage(null, msgData, mRoomId,p.getParticipantId());
    }          
}

Can someone please explain me why is it coming as unknown source ??

Just got it too. It will not happen if you specify a RealTimeReliableMessageSentListener in the first parameter of sendReliableRealTimeMessage. But updating to a new version of that library does bring annoying surprises :-(
