Ah, that will be caused by the recent refactoring of the raster classes.
Peter / Tim - can you suggest how to change the code to make it working again?

Today I've updated PythonBindings wiki page with some resources
(listed in top part in Using PyQGIS section). Basically it's good to
look at QGIS C++ API reference, QGIS blog, tutorials ported to Python
and QGIS plugins that have been done already. (all links listed there)
