OK, I've just tried this, and it's one of those annoying cases where it works
for me, but not for you. :-/

Yes, I tried that, too, and it just worked, so I'm wondering if something
is misconfigured somehow. Just for comparison, I have installed these
packages for PyQt4 and Qt Designer:

python-qt4         4.4.4-2ubuntu6    Python bindings for Qt4
python-qt4-common  4.4.4-2ubuntu6    Shared files for PyQt4
python-qt4-doc     4.4.4-2ubuntu6    Documentation and examples for PyQt4
qt4-designer       4.5.0-0ubuntu4.1  graphical designer for Qt 4 applications

I've also tried using both Python 2.5 and 2.6, and both worked.

Is there anything unusual about your Ubuntu installation?
