Having the following code:

import sys
sys.path.extend(('.', '/home/repos/python'))
from asn1.asn1 import *

ProfileLevel = SEQUENCE([('id', 0, INTEGER)],
  seq_name = 'ProfileLevel')


and trying to navigate to the INTEGER class declaration in asn1.asn1 module, the editor shows two choices: 

INTEGER in asn1.py
INTEGER in pgdb.py

Both modules are defined in /home/repos/python (and added in my Python Platform/Python 2.5/Python Path) 
but the import that I made was related only to asn1 with "from asn1.asn1 import *"

So navigation doesn't take into account only the symbols from the imports that I made, extending the search to 
all symbols scanned in the files of the Python Path.
