Summary: Inconsitent line numbering in traceback

Initial Comment:
Transcript below documents the problem.  

A traceback shows a line with no float() op, but 
complains of a float op error.  

I restart the shell, with no changes to the imported 
module, and this time line 45 is correctly listed.

>>> reload(brawley)
<module 'brawley' from 'C:\Documents and 
Settings\Kirby\My 
Documents\FreeGeek\PythonicGeom\brawley.py'>
>>> brawley.test2()
elems: 3, 4, 5, 0.5, 'White', 
sublist: 7,8,9]

['3', ' 4', ' 5', ' 0.5', " 'White'", ' ']
['3', ' 4', ' 5', ' 0.5', " 'White'"]

Traceback (most recent call last):
  File "<pyshell#28>", line 1, in -toplevel-
    brawley.test2()
  File "C:\Documents and Settings\Kirby\My 
Documents\FreeGeek\PythonicGeom\brawley.py", line 
45, in test2
    color = elems[-2]
ValueError: invalid literal for float(): 'White
>>> ================================ 
RESTART ================================
>>> import brawley
>>> brawley.test2()
elems: 3, 4, 5, 0.5, 'White', 
sublist: 7,8,9]

['3', ' 4', ' 5', ' 0.5', " 'White'", ' ']
['3', ' 4', ' 5', ' 0.5', " 'White'"]

Traceback (most recent call last):

45, in test2
    x,y,z,radius = [float(i) for i in elems[:-3].split(',')]
ValueError: invalid literal for float(): 'White

It's a little more serious.  After a save/reload, the traceback 
will echo code that's no longer present in the source at all.

Traceback (most recent call last):
  File "<pyshell#34>", line 1, in -toplevel-
    brawley.test2()
  File "C:\Documents and Settings\Kirby\My 
Documents\FreeGeek\PythonicGeom\brawley.py", line 45, in 
test2
    x,y,z,radius = [float(i) for i in elems[:-3].split(',')]
ValueError: invalid literal for float(): 'White'

But line 45 in the saved/reloaded source is really:
        x,y,z,radius = [float(i) for i in elems.split(',')[:-1]]

When I restart the shell and import, the real source code is 
echoed.
