This is a problem that I've been seeing for a while with Python and PyQt (outside of Maya) for a while now. Several other people have noticed it but Phil Thompson (PyQt creator) has yet to acknowledge that its an issue. It seems to plague some machines and not others for some unknown reason.
The only solution I've seen is to copy the DLLs from the PyQt4/bin directory to PyQt4 (ex. PyQt4/bin/QtCore4.dll --> PyQt4/QtCore4.dll) Its not an elegant solution but it should work. I haven't tried it with Maya but it works with Python command line. Cheers, -Scott -- http://groups.google.com/group/python_inside_maya
