Summary: UnboundLocalError in cgitb.py
Initial Comment:
Here's the exception:
Exception
return cgitb.text((E, e, tb)).rstrip('\r\n')
File "/usr/lib/python2.3/cgitb.py", line 197, in text
vars = scanvars(reader, frame, locals)
File "/usr/lib/python2.3/cgitb.py", line 76, in scanvars
parent = value
UnboundLocalError: local variable 'value' referenced
before assignment
And here's the code:
if lasttoken == '.':
if parent is not __UNDEF__:
value = getattr(parent, token, __UNDEF__)
vars.append((prefix + token, prefix, value))
else:
where, value = lookup(token, frame, locals)
vars.append((token, where, value))
elif token == '.':
prefix += lasttoken + '.'
parent = value
If lasttoken is '.' and parent is __UNDEF__, value doesn't
get set. I'd offer a patch, but I really have no idea what this
code is doing and so don't know what to set value to.

Jeremy, can you attach a complete test case?
Skip, I realize you didn't write the scanvars code (Ping
did), but you did add text. So maybe you have an idea.
>From a brief scan, it looks like if value is initialized to
None, the code might work.
