I recommed you to try the new QML features only on PySide git source, a lot of
bugs related to QML was fixed on mainline. A new release will be available on
next week.

fixed on pyside commit:
commit f7cb52d3822cb8d1897498cf04ca58813c530af6
Author: Renato Araujo Oliveira Filho <renato.filho@openbossa.org>

Created attachment 149 [details]

I did some changes on your example to get this running correct, check if these
changes are valid.

Thanks
