dumpTextureStats Console Function

I am trying to use the dumpTextureStats console function to dump out information for all the textures currently in memory. The problem I am having is that all of the textures that I have added to the project (except GUI images) have a probe->texFileName of NULL so my printout shows like the list below. Does anyone know WHY I am getting null for all my texFileNames?
