If you change the "styleSheet" by calling "setStyleSheet" on the window that has a menu using "QMaemo5ValueButton" as a pickselector, the selector will stop rendering its contents (title and current selection). As far as I can tell it does not matter what the new stylesheet changes.

To reproduce the error you only need to add one line to the example at: http://doc.qt.nokia.com/qt-maemo-4.6/maemo5-menu.html

I added to the last line of the MainWindow constructor:

setStyleSheet("QMainWindow

");

Attached you will find the modified version of the example
