TraitError: The 'gui_completion' trait of a SpyderIPythonWidget can't be a boolean?

[Dave Hirschfeld]

Just a quick heads-up: with the latest IPython & Spyder github versions I'm seeing the following error when trying to start an IPython kernel:

>>> Traceback (most recent call last):

Thanks Dave, another difference between 0.12 and 0.13. Will fix it right
away =)

Don't hesitate of keeping us posted of these kind of errors. I'm not
developing against IPython master but 0.12, so it's really good to know
them.

Cheers,
Carlos

Dave I just pushed some changes that should make our IPython console
work again. Please try them and let us know if they work for you.

Cheers,
Carlos

Works great, thanks for the quick fix!

Happy to keep you posted with any IPython 0.13dev issues. I'm running both IPython & Spyder from git/hg because they're both changing so rapidly and there's such great new functionality being added that hasn't made it to a release yet.

Cheers,

Dave
