Two bugs so far

-Device language selection is not respected, i.e. my n900 is set up to use English as device language and Bulgarian as regional settings. Stock clock shows dates in english (Mon, Tue,...) while replacement shows them in Bulgarian.
-on main screen buttons are missing, only text is there. But they are functional. I am using hydrocarbon theme.

EDIT: (slightly OT) I am pretty sure what causes second bug having im mind your merge requests for osso-calculator on gitorious. And i agree on pali's comment that hardcoding image names and bypassing sapwood engine is not a good idea. I have an idea (which I think is better) - to use somehow QT widget object name for setting underlying Hildon/GTK widget name, for example "pushButton1-HildonWidgetName-fremantle-stylus-button", so "HildonWidgetName" to be a key and the remaining string from objectName ("fremantle-stylus-button") to be passed to GTK paint engine, so sapwood to find correct images/colors. Still waiting MohammadAG to upload/clone QT 4.7.0 on gitorious (while trying to fix 4.7.2 raster bug). Once it is there I will try to implement such workaround which will allow QT apps on Maemo to have native Hildon look and feel.
