OK, I've reproduced a similar issue. The error/exception handling in that case was suboptimal 
and should have reported the original error message in the exception text. I've now fixed 
that in GDAL trunk and you'll get :

Traceback (most recent call last):
  File "test.py", line 6, in <module>
    lyr.CreateFeature(f)
  File "/home/even/gdal/trunk/gdal/swig/python/build/lib.linux-x86_64-2.7/osgeo/ogr.py", 
line 1479, in CreateFeature
    return _ogr.Layer_CreateFeature(self, *args)
RuntimeError: CreateFeature : unsupported operation on a read-only datasource.
