So according to Luciano Wolf the version 0.4.0-1maemo3 should have fixed the problem. There's already a slightly newer build than that in extras-devel: pyside-qt4 0.4.0-1maemo4 I recommend you install that one, it should hopefully make the error go away. Make sure you're not installing the "pyside" package. That one is totally outdated and irrelevant. I wished the pyside packages weren't such a mess. You need pyside-qt4, not pyside. And you want this: http://maemo.org/packages/view/pyside-qt4/ and not this (which is just the maemo5 module of Qt, not the complete bindings): http://maemo.org/packages/view/pyside-qt4-maemo5/
