[Andreas Kloeckner]

New submission from Andreas Kloeckner <inform at tiker.net>:

I get this debugger session with the attached file. Note that even
though a NameError occurs, no indication of that error is visible on the
debugger conosle.
8< -----------------------------------------------------------------
$ python -m pdb pdb_bug.py
> /home/andreas/tmp/pdb_bug.py(1)<module>()
-> def f():
(Pdb) n
> /home/andreas/tmp/pdb_bug.py(6)<module>()
-> list(f())
(Pdb) s
--Call--
> /home/andreas/tmp/pdb_bug.py(1)f()
-> def f():
(Pdb) n
> /home/andreas/tmp/pdb_bug.py(2)f()
-> print "BLAH"
(Pdb) r
BLAH
--Return--
> /home/andreas/tmp/pdb_bug.py(3)f()->None
-> bogus
