[Mono-list] Error in qyoto app

[Sharique uddin Ahmed Farooqui]

Hi,

I'm getting memory violation error in a qyoto application when I
calling slot. here is the code

Connect(btnCreatePlt, SIGNAL("clicked()"), this, SLOT("CreatePlt()"));

here is the code of slot
[Q_SLOT]
		public void CreatePlt()
		{
            some code;
		}

here is exception details in VCS Express (monodevelop and sharp
develop gives much shorter details on win7)
