[PyQt] PyQt4.QtGui + uuid.uuid4() = segfault

[Christopher Singley]

Sorry, I spoke too fast.  The issue persists on my system:

Python 2.7.1 (r271:86832, Dec  1 2010, 23:37:45)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from PyQt4 import QtCore, QtGui
>>> QtCore.PYQT_VERSION_STR
'4.8.1'
>>> import uuid
>>> uuid.uuid4()
Segmentation fault


Python 2.7.1 (r271:86832, Dec  1 2010, 23:37:45)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import uuid
>>> from PyQt4 import QtGui
>>> uuid.uuid4()
UUID('25599b3b-bc40-488f-ab9d-8beccde99def')

The workaround here is therefore obvious, but I'd still to figure out
what's going on here.  I don't have much experience debugging this
sort of issue, any hints?

TIA
