It sounds like the input processing does something funny with empty lines on Windows.

Can you perhaps provide a complete sample that reproduces the issue (without depending on imports that you haven't provided, ideally without anything outside the stdlib)?

PR #2447 is a big change of the input processing, so it may actually address this.

[takluyver]

The line that throws the error was already removed in #2783. If you've got time, can you try with the current development version of IPython, and let us know if the error is resolved?

[takluyver]

As the line that threw that error is long gone, I'm going to close this. Please re-open if you can reproduce the problem with an up-to-date version of IPython.
