I'm just starting my QGIS adventure, so don't take my word for it (I'm 
pretty decent Python programmer, but I don't know QGIS API fully yet)

 From what I observed QgsVectorLayer takes QString as a second

ShapeFiles. Also, you can test layer objects with isValid() method, see 
if it turns True or False.
