I've run into a strange situation with displaying text containing tab (\t) and newline (\n) characters in a QLabel.  The following code causes an immediate hard crash of python on my Windows XP system with Python 2.6, sip 4.10.5, PyQt 4.7.4, and Qt 4.6.3.  

from PyQt4.QtCore import *
from PyQt4.QtGui import *
import sys

app = QApplication(sys.argv)
dialog = QDialog()
layout = QHBoxLayout()

Removing either the tabs or the newline cures the crash.  The equivalent program written in C++ does NOT crash, leading me to consider that this might be a PyQt issue.  

How can I conclusively determine whether this is a Qt or a PyQt issue?
