Thanks for the info.

I forgot to mention my versions: Python 2.7.2, Qt 4.7.4, PyQt 4.8.5,
OpenSuSe 12.

So it could be a Qt bug introduced after Qt 4.6.2 or a PyQt bug
introduced after PyQt 4.7.2. Unfortunately (or not) I'm not a C++ guy
and don't know how to check if it is a Qt problem. Could someone
provide some more info, please? If it is a Qt bug I'd like to file an
issue in the Qt bug tracker.

Thanks.
