When I start spyder the internal console pops up and gives the following "traceback":
>>> WARNING:traitlets:kernel died: 6.001837253570557
Traceback (most recent call last):
File "C:\...\lib\site-packages\traitlets\traitlets.py", line 528, in get
value = obj._trait_values[self.name]
KeyError: 'banner'
During handling of the above exception, another exception occurred:

from IPython.core.usage import quick_guide
ImportError: cannot import name 'quick_guide'
The IPython console works without problems, it is just missing the "introduction text" (python version, help-commands).
Can I just ignore this exception or is there a way to fix this manually?
(Spyder developer here) This was fixed in Spyder 3.1.4 (just released). Please update to fix it.
