With 2.5, exceptions became new-style.  Unfortunately, 
the traceback module wasn't fully updated to still 
properly handle all (admittedly deprecated) string 
exceptions.  I noticed this because of its affect on 
unittest, where the original exception was masked.

Under 2.4.3:

>>> import traceback
>>> traceback.format_exception_only("strtype", 
"strvalue")
['strtype: strvalue\n']

Under 2.5b1:
>>> import traceback
>>> traceback.format_exception_only("strtype", 
"strvalue")

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    traceback.format_exception_only("strtype", 
"strvalue")
  File "C:\Python25\lib\traceback.py", line 168, in 
format_exception_only
    if issubclass(etype, SyntaxError):
TypeError: issubclass() arg 1 must be a class

I will also be entering a patch, but know that we need 
a bug number at this stage.
