After an update today I get

Downgrading to dev-python/prompt_toolkit-1.0.15 solves the issue, so it may be similar to https://github.com/jupyter/jupyter_console/issues/158

I haven't looked at the issue but probably. Because those are packages from the main tree, that's where it needs fixing. There is already an entry in bugzilla for this https://bugs.gentoo.org/669926 with links to more details. ipython <6 will not be compatible with prompt_toolkit >2. So main tree has to fix its dependencies.

Fixed in the main tree. Closing.
