I'm not sure what 'empty' means. If it means they're all red (or green), then it's a problem related to the theme.

One thing you might try: the program the loads the theme has to be run with a specific graphics system. On maemo5, IIRC, we used '-graphicssystem native', but I guess that depends on the platform - try the specific ones - 'raster' or 'opengl'.

I assume you have the theme installed ok? It's a separate package on gitorious.

Note that, if you don't have the theme daemon running, then the application will attempt to load it itself with built-in code. The daemon helps when you run multiple applications and widgetsgallery should work just fine without it. IE, you can ignore messages about failing to communicate with the daemon.

Note that we have some more widgetsgallery (etc) packages up on extras-devel for maemo5. Unfortunately, we put in the wrong 'Section' for meegotouch-demos-widgetsgallery, but you should be able to install it just fine from the command line. I expect we'll have the Section fixed tomorrow and so the Application Manager will notice it and set the 'update' icon flashing for people who have the previous version installed.

HTH.
