When you set the text, you fire a Changed event, which sets the text... etc

Add a flag that you can use to break the loop:

bool changingText = false;

protected virtual void OnTextBufferChanged(object o, System.EventArgs e)
{
    if (changingText)
        return;

    //do stuff

    changingText = true;
    this.textview1.Buffer.Text = temp4;
    changingText = false;
}
