Extras > Options doesn't display options (KDE Neon)

Hi Christian - have downloaded an run both versions of 2.22 (Oct 29th) and my problem persists. I've sent you a log. 

Dear Simon,

did this start with RC 2.20?
Are you seeing exceptions on the console when starting RouteConverter?

I can't remember which version it started with, but I tested it with 2.22, 2.21 & 2.20. The newest version I can run is 2.19 (to access options). 

If I run 2.20 from the console I see:

Code:

Logging to /tmp/RouteConverter.log

Many thanks.
