Not sure if this helps but it appears this problem only occurs on a 64-bit system. I did a Xenial 32-bit installation recently and the Python scopes (I tested calc: and manpages:) worked properly. On a Xenial 64-bit installation, even with the very last updates (especially the recent libunity-core), it still crashes.
