@stonebig, are you able to reproduce this one? It looks like a Qt issue to me.

I referred to this error in another issue (#5154). Then I discovered that the error, in my case, was occurring because I had set up another python interpreter, different from the default, and it did'nt have the ipython package.

@marcelotduarte, thanks for letting us know about it! Finally we have an explanation for this!

We'll take a look at it in 3.2.4

@marcelotduarte, I can't reproduce this. Please post the exact steps you followed to set up your another python interpreter.
