[John C. Tull]

Here is a debug message from trying out the plugin in a debug build  
with two shapefiles:

2/19/08 8:59:43 AM [0x0-0x13d13d].org.qgis.qgis[93141] An error has  
occured while executing Python code:

Traceback (most recent call last):
	File "/Users/jctull/.qgis//python/plugins/geoprocessing/ 
geoprocessing.py", line 187, in manageGui
		myListA = self.getLayerNames("all")
	File "/Users/jctull/.qgis//python/plugins/geoprocessing/ 
geoprocessing.py", line 424, in getLayerNames
		if layer.type() == QgsMapLayer.VECTOR and layer.vectorType() >=  
myType and not layer.name() in layerNamesList:
AttributeError: 'NoneType' object has no attribute 'type'
