Crash in QWidget::ensurePolished() method

Hi,

I'm experiencing a crash case for the following piece of code;

Qt Code:

Switch view

if(_imSessions.contains(remoteContactId)) 
	{
        controller = _imSessions[remoteContactId];
		if(controller != NULL){
			controller->showNormal();
		}
    }

if(_imSessions.contains(remoteContactId)) 
	{
        controller = _imSessions[remoteContactId];
		if(controller != NULL){
			controller->showNormal();
		}
    }

To copy to clipboard, switch view to plain text mode

Here is the related stack trace;

What might be the problem here?
