Just curious why the following two (seemingly similar) approaches using OGR 
Python access act differently.  Should it act that way?

This works:
 ...
 f1 = lay1.GetFeature(1)
 g1 = f1.GetGeometryRef()
 g1.ExportToWkt()

This seg faults:
 ...
 g1 = lay1.GetFeature(1).GetGeometryRef()
 g1.ExportToWkt()

Same issue with all the GEOS functions I was trying as well.  

Thanks for any thoughts,
Tyler
