Hi all!

I have a program that reads messages from a machine and places the messages in a QTreeWidget as QTreeWidgetItems.

The messages have multiple properties like: ID, Text, Type etc.
when the user clicks on the message (QTreeWidgetItem) it activates a slot and according to the message flags it should set the buttons enable or disable them but it crashes!!

  90.  
  91. 	}
  92. 	cout << "Ended" << endl;
  93. }

I can see where the crash happens because of the cout's. Like I see @7 when the flag is 7 but the cout << "Ended" never get executed and the program closes.

What can be wrong?

Thank in advance
