In your provider.select() call, what do you use for the spatial filter? 
If you want to run through all features in the layer, make sure you 
don't specify any bounds in the rect variable:

attrs = provider.attributeIndexes()
provider.select(attrs)

or if that doesn't work, specify the extent of the layer as the rect 
using layer.extent(), which is inherited from QgsMapLayer...

Cheers,

Carson
