Error when writing "yield"

[rockneurotiko]

I don't know if it's only me...

I've downloaded and installed from sources, I run ptipython, and start writing "yield", at the same time that I write the last character, I get that error:

You're right. Thanks for reporting this bug! I'll write a patch asap. (It's a bug in Jedi, I'll report it there and write a workaround.)
