Weird :/
I have to say I use Qt through the python bindings, but it was working before and now it doesn't. I guess the PyQt mantainers need to do some compilation magic.

What I found more worrying was that all references to those attributes (and all mentions of Maemo) have been scrubbed from the online docs at doc.qt.nokia.com/4.6. They are still available in the version at qt.nokia.com/doc/qt-maemo-4.6 . I'm sure in the past they were the same, so I freaked out a bit.
But if you say they are still there, I can relax
