Hello folks,
 
I ran into this by chance yesterday.  What is happening is if a module is imported from a directory but the current directory has a subdirectory of the same name as the module the __file__ attribute does not turn out right. 
 
example:
file showproblem.py:
 
import showproblem
if __name__ == "__main__":
...print "Name of __file__ is %s" % showproblem.__file__
 
if I run this within a directory without a subdirectory that has the same name as 'showproblem' everythings ok.
 
But if I run it in a directory with a subdirectory called 'showproblem', the __file__ is None.
 
Ive only verified it on Linux.  I suspected that the whole mechanism was broken for awhile but after some testing have narrowed it to this case.  I wager that for most of the time a user may not be affected by it.  But when it does hit, it is odd.  I couldn't get jyleo to run in my home directory because of this.  Python appears to do it ok, so Im pretty sure this is a bug.
