Can not show exception information correctly in IPython Console

[cheneave]

I'm using the dev version of Spyder, and ipython v3.1.0
When a ipython console is first started, it shows exception information correctly. For example, if I type in a undefined name, it shows a NameError.
But after I run a source file, even an empty source file, the console will only show

Traceback (most recent call last):

File "D:\Python\Python34\lib\site-packages\IPython\core\interactiveshell.py", line 3044, in run_code
except self.custom_exceptions:

TypeError: catching classes that do not inherit from BaseException is not allowed

When exception is thrown

I have found a very dirty workaround, just insert

self.custom_exceptions = tuple(
        [e for e in self.custom_exceptions if isinstance(e,BaseException)])

to line 3031 of Python34\lib\site-packages\IPython\core\interactiveshell.py

Is it because the method IPython handle custom exception is incompatible with python 3?

@cheneave, could you provide a step by step guide to reproduce this error?

[cheneave]

1. Create a empty script
2. Run it by pressing F5
3. type in any undefined variable such as "a"

It works properly before step 2

My version of python and ipython is

Python 3.4.3 (v3.4.3:9b73f1c3e601, Feb 24 2015, 22:44:40) [MSC v.1600 64 bit (AMD64)]
IPython 3.1.0 -- An enhanced Interactive Python.

Other packages required by spyder are all the latest version from pip3

This is an IPython upstream problem, not an Spyder problem. I'll see what I can do about it.
