I guess the newer version spoils your installation. My Xenial 
installation is build against python-sip 4.17 from the main ubuntu repo, 
and works fine.

It might be that python-sip 4.19.2 includes a different version of 
sip-api, which is of no use for you.

Try to downgrade python-sip, and libqt5core5a as well, which comes as 
5.5.1 from the main repo for me.

If KDE Neon does not provide it, try to force the main ubuntu repo version.

HTH,
