Qt 4.6.2 for Maemo 5 was released this week. Due to some changes prior to the final Qt release, PySide users might have seen this error when trying to use QtQui:
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: /usr/lib/pymodules/python2.5/PySide/QtGui.so: undefined symbol: _ZNK24QAbstractKineticScroller10metaObjectEv
To fix this, we rebuilt the PySide 0.2.3 packages against the Qt 4.6.2 release, and now it should be working again. So make sure you are using the latest PySide packages on Maemo 5 (0.2.3-1maemo3) and enjoy!
